Add `me` relation to social links

[jeromegamez]

Hi there 👋,

The Microformats spec says that

rel="me" is used on hyperlinks from one page about a person to other pages about that same person.

It's no hard argument, but at least Github adds this to URLs as well 😅, and Twitter recommends it in their developer docs (in the "Identify the Twitter profile of the page" section).

Thanks @jeromegamez, the links were helpful as well 🙂
