Utilities for overflow and object fit (#36848)

* Added "overflow-x" and "overflow-y"

- Having the same properties as overflow but for just the x and y axises
- Usecase being I want my y axis to be scrollable but not my x axis
- E.g a card with a vertical list of items.

* Added "object-fit" utilities

- The CSS object-fit property is used to specify how an <img> or <video> should be resized to fit its container.
- A responsive alternative to using background-img for a resizable fill/fit image.

* Updated documantation for the overflow utilities

- Now includes docs for `overflow-x` and `overflow-y` utilities

* Placeholder shortcode updated

- Can now choose to render an img tag or svg
- The image contains a base64 svg generated within the template
- example shortcode updated to detect, replace and render preview of 'img' tags as well

* New documentaion for Object Fit added

- Documentation added for the 'object-fit' util

* Updated spell checks issues

* Update object-fit.md

* Update overflow.md

* Update object-fit.md

* Updated markup to address HTML Validation Errors

- error: Bad value  for attribute "src" on element "img": Illegal character in scheme data: space is not allowed.
- info warning: Self-closing tag syntax in text/html documents is widely discouraged; it's unnecessary and interacts badly with other HTML features (e.g., unquoted attribute values). If you're using a tool that injects self-closing tag syntax into all void elements, without any option to prevent it from doing so, then consider switching to a different tool.

* Updated Fix

- Added Legibility to the img markup (example.html)
- Fixed issue with example not working properly (because image closing tag no longer has "/>" )

* update values by step of 0.25 in bundlewatch.config

The following values in .bundlewatch.config.json have been updated:
- ./dist/css/bootstrap-utilities.css
- ./dist/css/bootstrap-utilities.min.css
- ./dist/css/bootstrap.css
- ./dist/css/bootstrap.min.css

+description: Use the object fit utilities to modify how the content of a [replaced element](https://developer.mozilla.org/en-US/docs/Web/CSS/Replaced_element), such as an `<img>` or `<video>`, should be resized to fit its container.
+group: utilities
+toc: true
+---
+
+## How it works
+
+Change the value of the [`object-fit` property](https://developer.mozilla.org/en-US/docs/Web/CSS/object-fit) with our responsive `object-fit` utility classes. This property tells the content to fill the parent container in a variety of ways, such as preserving the aspect ratio or stretching to take up as much space as possible.
+
+Classes for the value of `object-fit` are named using the format `.object-fit-{value}`. Choose from the following values:
+
+- `contain`
+- `cover`
+- `fill`
+- `scale` (for scale-down)
+- `none`
+
+## Examples
+
+Add the `object-fit-{value}` class to the [replaced element](https://developer.mozilla.org/en-US/docs/Web/CSS/Replaced_element):
+
+{{< example class="d-flex overflow-auto" >}}
+{{< placeholder width="140" height="120" class="object-fit-contain border rounded" text="Object fit contain" markup="img" >}}
+{{< placeholder width="140" height="120" class="object-fit-cover border rounded" text="Object fit cover" markup="img" >}}
+{{< placeholder width="140" height="120" class="object-fit-fill border rounded" text="Object fit fill" markup="img" >}}
+{{< placeholder width="140" height="120" class="object-fit-scale border rounded" text="Object fit scale down" markup="img" >}}
+{{< placeholder width="140" height="120" class="object-fit-none border rounded" text="Object fit none" markup="img" >}}
+{{< /example >}}
+
+## Responsive
+
+Responsive variations also exist for each `object-fit` value using the format `.object-fit-{breakpoint}-{value}`, for the following breakpoint abbreviations: `sm`, `md`, `lg`, `xl`, and `xxl`. Classes can be combined for various effects as you need.
+
+{{< example class="d-flex overflow-auto" >}}
+{{< placeholder width="140" height="80" class="object-fit-sm-contain border rounded" text="Contain on sm" markup="img" >}}
+{{< placeholder width="140" height="80" class="object-fit-md-contain border rounded" text="Contain on md" markup="img" >}}
+{{< placeholder width="140" height="80" class="object-fit-lg-contain border rounded" text="Contain on lg" markup="img" >}}
+{{< placeholder width="140" height="80" class="object-fit-xl-contain border rounded" text="Contain on xl" markup="img" >}}
+{{< placeholder width="140" height="80" class="object-fit-xxl-contain border rounded" text="Contain on xxl" markup="img" >}}
+{{< /example >}}
+
+## Video
+
+The `.object-fit-{value}` and responsive `.object-fit-{breakpoint}-{value}` utilities also work on `<video>` elements.
+
+```html
+<video src="..." class="object-fit-contain" autoplay></video>
+<video src="..." class="object-fit-cover" autoplay></video>
+<video src="..." class="object-fit-fill" autoplay></video>
+<video src="..." class="object-fit-scale" autoplay></video>
+<video src="..." class="object-fit-none" autoplay></video>
+```
+
+## Utilities API

 Using Sass variables, you may customize the overflow utilities by changing the `$overflows` variable in `_variables.scss`.
