Create useIsInView

[VictorGa]

Create a hook called useIsInView that uses the useIntersectionObserver.

This hook will return true/false for when the element passed is in view

[ReneDrie]

The useIntersectionObserver hook used in our skeleton (see here is currently returning a boolean for the inView state which I use more than the callbacks personally.
Not sure if people agree that this should be the default, if not, then this hook would definitely be needed.
I think we need to find the best way one remove one implementation.
