Subject: [PATCH 1/3] PermissionGrid fixes

Fixes https://github.com/flarum/core/issues/3169#issuecomment-979470794

- Restore wrapping `scope.render` results in a table cell tag. This was accidentially introduced in 924815b6e1f01cf709212d58ded1badd3e03779c, and caused the issue linked above
- Rename the `SettingDropdown` attr `key` to `setting` in order to avoid naming clashes with Mithril vnode keys. `key` still works, but is deprecated.
