forge-alist: support ssh.github.com

[gekoke]

GitHub remotes can be configured using the ssh.github.com domain. When configuring a GitHub remote using SSH authentication behind a firewall that messed with port 22 using the steps outlined here, forge was unable to determine the correct forge.

I remidiated this with (add-to-list 'forge-alist '("ssh.github.com" "api.github.com" "github.com" forge-github-repository)) in my config.

Perhaps this value should exist by default in the alist?

Thanks for making me aware of this potential complication!

I'm undecided whether to add an entry to forge-alist and/or a note to the documentation somewhere. It has been a struggle to find the right balance in the past. Before I added additional information about complications affecting only a small subset of users, people told me that there was not enough documentation. After I added such information, people told me there was too much irrelevant information and they started asking for simple tutorials, and I noticed that many stopped reading even the parts that were relevant for everyone.

I'll let this marinate a bit, before deciding what to do.

Thank you for your consideration!

The fix in this case was, admittedly, a relatively easy and permanent one.
