Publish 2.3.1 to use as go module

[RobKenis]

Proposal

Publish v2.3.1 to https://pkg.go.dev/github.com/percona/percona-postgresql-operator/cmd/postgres-operator.

Use-Case

I am writing an operator that uses the PerconaPGCluster types. They are available in v2.3.1, but the latest version to import is v1.5.1

Is this a feature you are interested in implementing yourself?

Yes

Anything else?

I could do this myself if I knew how to do it. If given guidance, I do not mind picking this up myself.

Oh, it seems to be autogenerated. We will fix it.
@inelpandzic once you have time, please have a look.

@spron-in Thank you 🙏 I am now using github.com/percona/percona-postgresql-operator v0.0.0-20240122085308-8253f681478d which is not very elegant, but I am no longer blocked on this.
