feat: add release reactions and a GitHub-like reaction bar (#38415)

Adds emoji reactions to releases and moves the reaction picker of
issues, comments and releases into a GitHub-like reaction bar.

- Releases omit 👎 or 😕
- Drafts and tags can't be reacted to
- Moved menu to tippy
- Added keyboard navigation
