DEV: Convert approve_new_topics_unless_trust_level to groups (#24504)

* DEV: Convert approve_new_topics_unless_trust_level to groups

This change converts the `approve_new_topics_unless_trust_level` site
setting to `approve_new_topics_unless_allowed_groups`.

See: https://meta.discourse.org/t/283408

- Hides the old setting
- Adds the new site setting
- Add a deprecation warning
- Updates to use the new setting
- Adds a migration to fill in the new setting if the old setting was
  changed
- Adds an entry to the site_setting.keywords section
- Updates tests to account for the new change

After a couple of months we will remove the
`approve_new_topics_unless_trust_level` setting entirely.

Internal ref: /t/115696

* add missing translation

* Add keyword entry

* Add migration
