fix: avoid y-axis clipping for branch name (#6817)

- `gt-ellipsis` is set on elements to avoid overflowing its text contents and in the case of overflowing it would show an ellipsis. To force it to not overflow `overflow: hidden` is set, however this also hides the overflow on the y-axis, `overflow-x: hidden` has the same behavior.
- To avoid avoid the branch name from being clipped, add a very small amount of padding on the y-axis. This is a workaround and not a proper solution. There does not seem a good cross-platform solution available to fix this in a proper way.
- Resolves forgejo/forgejo#6811
