Upgrade is-plain-object to v5.0.0 (#4500)

* Upgrade `is-plain-object` to v5.0.0

The `is-plain-object` package recently had a major version upgrade that
broke libraries which import its default export, such as this one. This
causes issues when other packages in the same application require a
higher version of `is-plain-object`, resulting in an error originating
in Slate's codebase. To remedy this, Slate is now depending on
`is-plain-object@^5.0.0` and its import references across the codebase
have been updated.

Fixes #4499

* Add changeset
