As part of validating the module name and version for the new submission pipeline that supports modulectl, we need to check if a newer version already exists. Due to changes in the folder structure for the new submission pipeline, a new script is required to retrieve the list of existing versions of the module.

existing retrieve new and old module version code:

Reasons

Support new submission pipeline for the modulectl
