General: Update English Gravatar links.

Replace links to en.gravatar.com with links to gravatar.com as the english site now uses the base domain. This avoids an unnecessary redirect for english language sites.

The links remain translatable for non-english versions of WordPress.

Props narenin, knutsp.
Fixes #61424.
