An earlier change added init_worktree_config() as a helper to initialize extensions.worktreeConfig if not already enabled. Let the sparse-checkout builtin use these helpers instead of attempting to initialize the worktree config on its own. This changes behavior of 'git sparse-checkout set' in a few important ways: 1. Git will no longer upgrade the repository format, since this is not a requirement for understanding extensions.worktreeConfig. 2. If the main worktree is bare, then this command will not put the worktree in a broken state. The main reason to use worktree-specific config for the sparse-checkout builtin was to avoid enabling sparse-checkout patterns in one and causing a loss of files in another. If a worktree does not have a sparse-checkout patterns file, then the sparse-checkout logic will not kick in on that worktree.
