UI: Tweak tab text and icon colors

[silverwind]

This adds a hover highlight and fades out inactive tabs.

Updated. Turns out the dark theme already had this hover effect implemented, so I removed the styling there and simplified it a bit.

Sorry, had to do one more minor tweak. Inactive tabs are faded out a tiny bit more now (.5 over .6):

Anything blocking the merge here?

[techknowlogick]

@silverwind once the conflict has been resolved, I can merge this.

[silverwind]

It's the damn CSS file as always (#6782), rebased, regenerated and force-pushed.

[techknowlogick]

Merged. Thanks for your contribution 😄. I will also take this time and suggest to you that you'd make a great candidate for a maintainer of Gitea. One benefit would be you'd be able to provide reviews on other PRs. The only requirement is that you participate in one PR review every few months, or contribute code in the same time frame (which you already meet). I understand it is asking for a minor time commitment, and so please don't feel pressured to accept.

[silverwind]

Guess I can do that. Just put up a PR to add myself to maintainers file?

[techknowlogick]

@silverwind yup
