Remove both `git::LoadMoreHistory` and `git::ViewCommitFromHistory`
actions as although both actions were registered in the workspace, they
don't actually have effect when run.
This appears to have been leftover from
https://github.com/zed-industries/zed/pull/42441 , possibly the initial
implementation on how to open a commit and load more commits when the
file history view was open, which is now handled with `Button.on_click`
callbacks instead of relying on actions.
Closes#49288
Release Notes:
- Removed unused git actions – `git: load more history` and `git: view
commit from history`
