Add back hover states on example items

[ejsandoval]

The example items on the Examples index are missing hover state interactions. Add either block background or change of opacity on hover.

@ejsandoval Is this issue still on? Can i work on this?

[ejsandoval]

@praveen-rikhari Yes! It's still ongoing. When navigating the Examples index, we need some hover state feedback for the user. I added a video for reference on where this should have interaction feedback.

Hi, I've submitted a PR #554, that addresses the hover animation for the images as discussed in this issue. Let me know if there's any feedback or changes needed. Thanks
