Requesting to fix Debian FAQ Chapter 5. Software available

Hi,

There are a few issues with Debian FAQ Chapter 5. Software available in the
Debian system.

Specifically:
 - A broken link to 'Debian mirrors'.
 - References from 2016 about changes to Dan J. Bernstein licenses that are
no longer relevant.
 - References to gnash, googleearth-package and ekiga packages that are no
longer available.

I have local changes ready to be submitted as a merge request if someone
can approve my registration in Salsa.

I'm looking to do a lot more work on Debian but don't want to overstep.
Where's best to send a lot of questions and requests to make changes to
docs and the wiki, either by email or IRC?

Thanks,
Harry
