Comment:

 [attachment:"47577.diff"] makes the following changes:

 * Introduce `wp_is_using_https()`, which detects whether the site uses
 HTTPS based on the WordPress site URL.
 * Introduce `wp_is_https_supported()` which detects whether HTTPS is
 supported by the environment (using a cached request to the HTTPS version
 of the site).
 * Enhance the Site Health test for HTTPS status to use the new function
 and provide accurate recommendation based on the results.
 * If HTTPS is active, filter and replace non-HTTP links to the site in
 content with their HTTPS counterparts.
