Sergey Biryukov 1aa22ca3c6 Taxonomy: Correct the check for error messages in wp-admin/edit-tag-form.php.
Instead of checking for a specific message, e.g. “Item not updated”, the `$_REQUEST['error']` variable is now checked. This allows for custom messages added via the `term_updated_messages` filter to be considered an error when appropriate, and displayed with the correct CSS class.

This also brings consistency with a similar check in `wp-admin/edit-tags.php`.

Follow-up to [31823], [44663].
