Simplify regular expression for checking URL validity to just do basic checks to confirm the value looks like a URL.

Weston Ruter	ca12fb6710	Customize: Fix reliability of just-in-time publishing for changesets that miss their schedule when visiting `customize.php`. When just doing `wp_publish_post()` for the changeset from `customize.php`, any option-based settings will fail to get saved because `WP_Customize_Manager` would have already been loaded with `settings_previewed`, resulting in `update_option()` calls being short-circuited. So an admin-ajax request to `customize_save` is used to work around this. Props westonruter, jeremyfelt, dlh for testing, LittleBigThing for testing. Amends [41626]. See #28721, #39221.
