Fixes an issue where I was missing some brain cells and changed the git
panel's `render_entries` to a `v_flex` instead of an `h_flex`.
But actually, fixes the git panel entries from disappearing when a
scrollbar is rendered.
**Before**

**After**

Closes #25955
Release Notes:
- Git Beta: Fixed an issue where when the git panel would need to scroll
all the items are pushed off the screen.
