v5: Add role=button cursor in Reboot (#31040)

* v5: Add role=button cursor in Reboot

Ports the changes from #30562 made in v4.5 and adds them to v5. This replaces #30563 which sought to add this to the utility API, but the v4 PR shifted to implement an accessible solution vs a lone utility.

* Update reboot.md

+### Pointers on buttons
+
+Reboot includes an enhancement for `role="button"` to change the default cursor to `pointer`. Add this attribute to elements to help indicate elements are interactive. This role isn't necessary for `<button>` elements, which gets its own `cursor` change.

+{% capture example %}
+<span role="button">Non-button element button</span>
