ui: Improve focused border color consistency across panels (#44754)

Devzeth created

The issue is that we aren't consistent in using the same
`panel_focus_border` color across zed.
Might completely fix my issue: #44750 

For focused items in: 
- outline panel
- git panel

While these: 
- project panel
- keymap editor tab

Are actually using the panel_focused_border option. 

Not sure if this warrants a release note, feel free to adapt. 

Release Notes:

- N/A
