Doesn't work with Git worktrees

[ecraig12345]

If I open the root folder of a Git worktree in VS Code, open a file, and try to use any of the commands to copy a link, I get an error The workspace at 'file:///Users/me/git/my-repo-worktree' is not tracked by Git. The commands work fine in the main local copy of the same repo.

Worktrees are implemented with a .git file which points to the the actual directory:

/my-repo-worktree
  .git            file with contents: 
                  gitdir: /(actual path here)/my-repo/.git/worktrees/my-repo-worktree

/my-repo
  .git/
    worktrees/
      my-repo-worktree/
        (normal .git folder stuff)

So this line ought to allow .git to be either a file or directory.

Then if all you're doing is running git commands, that can be done from the root of the worktree. (Only need to bother with looking in my-repo/.git/worktrees/my-repo-worktree/ if you need to dig into the .git folder contents, which I'd guess isn't needed?)

This is now available in v2.1.0 which has just been published to the marketplace.

Thanks again for the contribution, @ecraig12345! 😁
