Describe what you would like us to do:

The docs mailing list is moving to Discussion. I'm not sure who's an admin these days, so can you please make a few changes?

1. Disable new subscriptions (optional, I suppose)
2. Disable posting to the list
3. Update the description to read:

This mailing list has moved to Fedora Discussion: https://discussion.fedoraproject.org/tag/docs
This list is for writers, editors, translators, and developers discussing everything related to documenting an open source OS, including peer editing, publishing tools, and so forth.

When do you need this to be done by? (YYYY/MM/DD)

Let's say 2022/01/31 just to put a date on it.
