Improve commit status icons (#21124)

- Show popover on hover/focus (tippy default) instead of click
- If there is only one status, add href to trigger element
- Increase tippy
[interactiveBorder](https://atomiks.github.io/tippyjs/v6/all-props/#interactiveborder),
making it easier to keep interactive tooltips open with sloppy mouse
movement
- Fix a overflow issue in the commit list
