106352: roachtest: allow cockroach-ephemeral in roachprod-stress r=srosenberg a=tbg

`andrei-jepsen` is very low on quota, and `cockroach-ephemeral` is no
longer used by the nightlies but is well-quotaed, so we should use it
instead.

Remove an old tripwire that tried to prevent folks from using
`cockroach-ephemeral`.

Epic: None
Release note: None
