Show "(hooks disabled)" in title bar of commit message editor (#4467)

- **PR Description**

It is shown either when committing with `w`, or when typing the skipHooks prefix
if there is one. This should hopefully make it clearer when the hooks are run
and when they are not.

```
╭─Commit summary───────────────────(hooks disabled)─ 7 ─────╮
│WIP foo                                                    │
╰───────────────────────────────────────────────────────────╯
```
