Doesn't work within a git worktree

[eramdam]

This extension is very useful in my day-to-day, thanks! However, I started to use git worktree and I noticed the extension doesn't work when the currently opened folder is a work tree.

You can reproduce by doing the following in an existing repo

git worktree add ../my-worktree "branch"

and trying to use the action inside the newly created folder inside of VSCode, the action will fail because of the lack of a .git/config file

My guess is that you could work around this by using the current workspace's absolute file as a fallback 😁
