Coding Standards: Remove unnecessary annotations for __ngettext() and __ngettext_noop().

Since PHPCompatibility 9.3.2, the `ReservedFunctionNames` sniff skips functions with a `@deprecated` tag.

Reference: [PHPCompatibility/PHPCompatibility#917 WPCS: ReservedFunctionNames: ignore deprecated functions].

Follow-up to [46290].

Props rodrigosprimo.
See #64627.
