doc-diff: force worktree add

We avoid re-creating our temporary worktree if it's already
there. But we may run into a situation where the worktree
has been deleted, but an entry still exists in
$GIT_DIR/worktrees.

Older versions of git-worktree would annoyingly create a
series of duplicate entries. Recent versions now detect and
prevent this, allowing you to override with "-f". Since we
know that the worktree in question was just our temporary
workspace, it's safe for us to always pass "-f".
