feat(whitby): Serve static HTML dir for deploys.tvl.fyi r/2837

Add a new domain and nginx virtual host at deploys.tvl.fyi, serving out
of a static directory on whitby which is created by systemd-tmpfiles.

This will be used to serve diffs rendered by nix-diff for
pending deploys for whitby

Since this contains stateful data, it is added to the restic backups
on whitby.
