Re-license documentation as CC-BY
At the moment, our documentation is licensed as AGPL like pleroma itself. This can be a problem for people who run wikis or blogs and don't want to put their whole writings under the AGPL too. Let's relicense under CC-BY, which should be good enough for our purposes but also make it usable essentially everywhere.
Steps for this
- Find all the people who contributed to the docs
- Contact them and get them to make a commit confirming that they agree to license their doc contributions under CC-BY
- If we can't find them all or get them all to do it, rewrite the parts that are left
