 Gravatar now seems to support the sha256 hashing algorithm.

 Source https://docs.gravatar.com/general/hash/

 Functions such as `get_avatar_data()` use the old md5 hashing algorithm.
 That's still supported by Gravatar but considering the md5 string can be
 reversed, privacy may be impacted in cases where a user's email is
 obtained from the md5 hash.
