Site Health: Update loopback test to `POST` to wp-cron.

Replace loopback health check URL with a `POST` request to `wp-cron.php` in the WordPress install directory. This more closely represents how WordPress uses loopback requests.

A `POST` request is used to cause `wp-cron.php` to exit prior to running any cron jobs. This allows the test to indicate success quicker and accounts for sites that set the `DISABLE_WP_CRON` constant to avoid running cron jobs on loopback requests.

Props clorith, peterwilsoncc, TimothyBlynJacobs.
Fixes #52547.
