docs: connect to praefect database
What
Update document on how to connect to the praefect database
Why
To connect to the database we need ssl certificates that only root
can
read. The dbconsole-praefect.sh
script automates this for us.
All the other alternatives will no longer work since we turned on ssl_mode to be required https://gitlab.com/gitlab-com/gl-infra/production/-/issues/8308, meaning only allow connections via SSL.
