Remove stable/2023.1 job from master gate

stable/2023.1 is planned to be in unmaintained state[1]
and with python 3.8 drop from Tempest[2], we have to pin the
Tempest for stable/2023.1 testing[3]. This means Tempest and
its plugin master does not need to support stable/2023.1.

With that we can remove the stable/2023.1 jobs from tempest
plugin master jobs.
