Add focusgroup attribute as valid prop

[djmarland]

What:

Adding focusgroup to the list of valid props

Why:

focusgroup is an upcoming attribute for HTML elements.

Currently, we are unable to test & use this attribute as it fails the is-valid-prop check in Linaria

How:

Simply adding to the allow-list. No logic changes.
