Update hover effect of group component

This is the expected output of the hover animation of cards.

Hi @aastrong,
Can you test his code on your local and adjust the animation from the MR to get the same as design's gif from @kenyoOwen?
Thanks!

Will create a new branch for tugboat environment.

This is now ready for review.
