Comment:

 `mysqlnd 5.0.9` or later supports `utf8mb4`. This is noted when `mysqlnd`
 appears in the client info [https://github.com/WordPress/wordpress-
 develop/blob/6.1/src/wp-admin/includes/class-wp-site-
 health.php#L1377-L1378 Ref]. When `mysqlnd` does not appear in the client
 info, then the `libmysql` recommendation is made.

 Before upgrading to use PHP 8.2, server administrators should already be
 aware of the need to change to `mysqlnd` for `utf8mb4` support on PHP
 8.2+.

 The version of `mysqlnd` is the same as the PHP version
 [https://github.com/php/php-
 src/blob/7b4c7374c3d3adfb690d951f5224ba0f27200364/ext/mysqlnd/mysqlnd.h#L22
 Ref], so this shouldn't be a problem when using PHP 8.2+.
