Since we don't intend to turn on auto-release any time soon, we need the equivalent but triggered by a human.

WIP started here:

https://gitlab.cee.redhat.com/rhidp/rhdh/-/merge_requests/113

Doc updates can start here and continue in RHIDP-5303.

TODO:

• push updates to the stage index for 4.18 so we can validate if the fix works for RHIDP-5107
• implement the TODOs in the kfuxRelease.sh script
• doc updates, including refactoring and removing all the CPaaS/GL pipeline leftover that don't apply any more - https://gitlab.cee.redhat.com/rhidp/rhdh/-/blob/rhdh-1-rhel-9/docs/RELEASE_GUIDE_1.3.adoc?ref_type=heads created to hold the pre-Konflux instructions
