  worktree: switch over worktree pruning to an opts structure The current signature of `git_worktree_prune` accepts a flags field to alter its behavior. This is not as flexible as we'd like it to be when we want to enable passing additional options in the future. As the function has not been part of any release yet, we are still free to alter its current signature. This commit does so by using our usual pattern of an options structure, which is easily extendable without breaking the API.
