[PATCH 10/10] submodule ensure-core-worktree: write to config.worktree

["Nguyễn Thái Ngọc Duy" <pclouds@gmail.com>]

Use repo_config_set_worktree_gently() to write core.worktree. If the
submodule has extensions.worktreeConfig on, the key will be in
config.worktree instead of config file and not affect any new
submodule's worktrees.
