[develop]: Remove shell workflow.

DESCRIPTION OF CHANGES:

This PR removes the shell workflow. Almost all of the duplicate files under ush/ are removed, choosing either the shell or python version. Two files still need both versions since it turned out to be difficult to use the python versions in job scripts without regional_workflow environment activated there. The PR will make updates much easier because there is only one workflow generation path to worry about.

TESTS CONDUCTED:

I have run tests successfully on HERA, ORION and JET. The set of tests are taken from a recent run using the shell workflow generation path done in PR #744 slighltly modified to use the new "custom_ESG/GFDLgrid" names.
