* `gettext_{$domain}`
* `gettext_with_context_{$domain}`
* `ngettext_{$domain}`
* `ngettext_with_context_{$domain}`
Additionally:
* Pass `$domain` parameter to the new hooks, for consistency with their pre-existing counterparts.
* Update documentation to explain the dynamic portion of the filter, for consistency with other dynamic hooks in core.
Follow-up to [48131].
