Workflow to publish to community-operators

[djzager]

We need a workflow, executed when needed (ie. workflow_dispatch), that would submits a PR to https://github.com/k8s-operatorhub/community-operators/tree/main/operators . The constraints:

• We want sha digest pinning. This means that each of the relatedImages must be mirrored to quay with a particular tag (to keep the sha from being garbage collected). Image tags in the CSV should be updated to use sha digests
• Should accept the version (ie. vX.Y.Z-abcd.1234) as input
