Official Mastodon Ansible playbook not documented as a deployment option

[thunderysteak]

The Mastodon Ansible Playbook is a quick and easy way of deploying and patching Mastodon instances and looks like not a lot of people are aware of it.

It works on Ubuntu 20.04, Ubuntu 21.04, RHEL 8 derivatives and RHEL 9 derivatives with builds passing

I feel like this should be included in the docs

I think it's recently been uplifted and having active development again, so it's probably a good idea to add it to the docs, yeah.
