WordPress/wp-admin/options.php
Peter Wilson 6876d19129 Options, Meta APIs: Prevent saving of invalid timezones.
Prevent the saving of invalid timezone string in to the database on the options pages. If an invalid timezone is submitted it is ignored and the setting remains unchanged.

This prevents a warning or fatal (depending on the PHP version) from being thrown by an invalid timezone setting on the Settings > General page.

Props ankit-k-gupta, costdev, huzaifaalmesbah, mrinal013, nicolefurlan, oglekler.
Fixes #58814.
