Discord is a great way of receiving help for members of the community
that are not on the mailing list or not familiar with Libera.

Adding it to the official documentation will aid discoverability of it.

The link is the same as the one at https://git-scm.com/community.

This matches the result of my local fixup (you could have just said
YesPlease when I said that I'll locally fix-up).  Will replace.

Thanks.
