FEATURE: Localizable /about page fields via its settings page (#41123)
The /about page (unlike /guidelines or /tos) is not backed by a topic,
but instead via a bunch of site settings.

If it were backed by a topic, localization would be easy as it can just
use TopicLocalizations. We also can't swap it out to use a topic, since
there are so many fields on the about page that can't be safely
contained in a topic.

----------

This PR adds SiteSettingLocalization, allowing new attributes in site
settings config for localization.

For now this is wired into the About page settings flow:
  - admins can select a non-default locale on /admin/config/about
  - only translatable About fields are shown for that locale
  - localized About values are used on /about and /about.json
- company_url can be set manually per locale, but is excluded from
automatic translation
- ~~AI backfill can translate eligible site setting localizations~~ no
backfill (added in

about page has very non automa-ble fields

This intentionally keeps the scope narrow. It does not make every site
setting localizable, and any other setting can be localized by adding to
that allowlist.
