Updated the site api endpoint

[enejb]

Update to be the same as the recent changes on .com to the setting api endpoint.

To test
Go to https://developer.wordpress.com/docs/api/console/

and request the endpoint
/sites/$siteID

Notice that it returns the same data as /me/sites for a particular site.

Change constants to something else.
Retest.

I think this doesn't quite work as expected yet.

@lezama and @roccotripaldi can you test this to make sure we get what we expect here? And also make sure that the code makes sense?

To test on https://developer.wordpress.com/docs/api/console/
I tested the /sites/123456789 api endpoint.

having this defined in wp-config.php
define( 'FS_METHOD', 'ssh2' );
define( 'DISALLOW_FILE_EDIT', true );
define( 'DISALLOW_FILE_MODS',true );
define( 'WP_AUTO_UPDATE_CORE', false );
define( 'AUTOMATIC_UPDATER_DISABLED', true );

gives me

:yoda: style

Other than the typo in the variable, this is looking good.

I've tested on a few different sites, with different combinations of defined constants. It is working as expected.

Fixed the typo and hopefully clarified the comment.

Looks good @enejb !
