Subject: [PATCH] Upgrade/Install: Add port number to target origin when
 decrementing update counts.

This ensures that the update counter bubble in the admin menu is properly decreased after a successful plugin or theme update from within the update iframe when the site uses a non-standard port number.

Follow-up to [27280], [29357].

Props TobiasBg.
Fixes #59987.
