Update FAQ about hidden services with OnionShare information
Currently we say:
Can I run a Tor hidden service on Tails?
It is technically possible to use Tails to provide a hidden service but it is complicated and not documented yet.
For example, some people have been working on how to run a web server behind a hidden service on Tails. See #7879.
Maybe we can add something about being able to share files through an onion service easily with Onionshare?
It would be a matter of pointing to https://tails.boum.org/doc/anonymous_internet/onionshare/
