Clarify docs on what silopub does with the "name" for Facebook

[aaronpk]

https://silo.pub/developers#vocab-facebook says:

name - title of an article. If name and content are provided, then silo.pub will post the full text.

Does this mean the name will be included in the body of the post on Facebook? I didn't think Facebook posts had a separate "name" property so that's how I would imagine it would work. I'd appreciate a more specific description of what happens in the docs.
