Let's encrypt will support certificates without common name starting at 2023-11-29. Details see in this announcement. It allows to create certificates for domains longer than 64 characters without needing to set the common name to a shorter domain name.

This PR makes small adjustments to the certificate ordering to reflect the new possibility. The common name is only set if the first domain name is shorter or equal than 64 characters. Therefore the change should be compatible with the current usage.

Note: The new behaviour can already be tested on the staging server (https://acme-staging-v02.api.letsencrypt.org/directory)

Fixes #2049

I was confused by this change https:/go-acme/lego/pull/2054/files#diff-49d368acbbb16528a9b447c4cbb44c3901b0636333a15e42117bc5184a28ec5cR284

But this PR is incomplete, I will add the missing pieces.
