[ROSAENG-1452] Automating Managed Platform maintenance for ocm-agent-operator

Summary

In this ticket, we'll want to optimize some of the maintenance work for ocm-agent-operator such that the amount of time spent by the team is reduced and the maintenance task for the operator is streamlined. 

We can re-use the script that's used for MUO script https://github.com/openshift/managed-upgrade-operator/blob/master/hack/maintenance-update.py 

ACCEPTANCE CRITERIA:

Automate maintenance for ocm-agent-operator to be able to easily handle maintenance per OCP release with minimum effort in a standardized way.

Operator repo docs are updated accordingly

NON GOAL:

We are not to update the deps specific to a OpenShift release yet. That will be done separately. For now, it's only about updating the existing deps and having boilerplate validations.

Start by reading hack/maintenance-update.py in the managed-upgrade-operator repository and inspect the ocm-agent-operator repository's existing maintenance and dependency documentation. Done means a standardized automation workflow handles existing dependency updates and boilerplate validations for the operator, with the repository documentation updated; OpenShift-release-specific dependency updates remain out of scope.
