For folders and files basically any selected item in the git panel we
draw a border around it. The issue is that the right side of this border
wasn't ever visible.

In the project_panel.rs file I've saw that the decision was to make the
right side border 2 pixels. And this panel doesn't have this issue, no
matter which side of the dock is selected. So it was a very easy `look
at how we did x do y`.

I don't think it warrants a release note.
