ability to sign Rego policies before pushing them to the OCI registry

[developer-guy]

Hi, we (w/@dentrax) thought that it'd be nice to add the ability to sign Rego policies before pushing them to the OCI registry by using the cosign^1 project under the hood. A while ago, we opened a similar issue to the ÒPA Gatekeeper`^2 project.

Makes sense to me, would be a welcomed enhancement!
