Add h-card to support the IndieWeb movement

[pfefferle]

Adds the h-card (microformats) markup to the "follow me" widget. With the actual card feature it might replace the posts author markup and therefore it might be nice to support other movements aside from the fediverse.

The h-card is mainly used by Webmentions (and a lot of other IndieWeb specs), to detect the author of a blog post.

The change are only made to the user facing site, because they do not interfere with the design and do not bring any need in the editor mode.

Some further informations:

• h-card Spec: https://microformats.org/wiki/h-card
• Test Parser: https://php.microformats.io/

Proposed changes:

• Add semantic HTML markup to the "Follow-Me" block

Other information:

• Have you written new tests for your changes, if applicable?

Testing instructions:

• Add a follow me card to a page
• Copy & Paste the HTML to the linked parser
• Check the result
