Merge branch 'bugfix/110-mastodon_broken_certbot' of kosmos/chef into master

This is already done in the certbot vhost
(https://gitea.kosmos.org/kosmos/chef/src/branch/master/site-cookbooks/kosmos-nginx/templates/default/nginx_conf_certbot.erb)
and it redirects every request to HTTPS, breaking Let's Encrypt
validation

Fixes #110
