Remove beta.impress.openneo.net from deploy setup

We're now all-in on impress.openneo.net for this box!

One little wrinkle is that certbot was initially upset that I had
already uploaded the copy-pasted certs from the other box to here, at
the file path it expected to get to manage. So, I moved those to
`/srv/impress/shared/temp-certs`, and changed the nginx config
accordingly; and then deleted the original and let certbot control it!
