Description

Fixed the hover and active states.

Notes

I found out that --color-state-information-hover used for the hover background doesn't exist. When I used the tokens for accent hover/active, it looked more like what it should have looked like all along. We can remove that if it's not relevant, but it seems to resolve all of the hover state issues to what was likely originally intended.
