General: PHP7.3 throws an `E_WARNING` when using continue to target a switch

Applying continue to a switch is equivalent to using break and quite possibly, a continue targeting a higher level control structure is actually intended.

To target the higher level control structure, a numeric argument has to be passed to continue. This fixes two cases in WordPress Core where this is currently happening.

See: https://github.com/php/php-src/pull/3364
See: https://wiki.php.net/rfc/continue_on_switch_deprecation

Props jrf.
Fixes #44543.
