Site Health: Include both site and user locales in debug information.

Previously, only the site’s locale was displayed in the Site Health debug information. Moving forward, both the site’s default locale and the user’s locale will be specified.

This change also removes the `@param` tag for `WP_Debug_Data::debug_data()`. This parameter was previously removed in [45156].
