This teaches the `worktree repair` command to respect the `--[no-]relative-paths` CLI option and `worktree.useRelativePaths` config setting. If an existing worktree with an absolute path is repaired with `--relative-paths`, the links will be replaced with relative paths, even if the original path was correct. This allows a user to covert existing worktrees between absolute/relative as desired.
