BASH GitHub CLI version of High Resolution cases used for CI weekly t…

…ests (NOAA-EMC#1869)

A BASH script using  **GitHub CLI** is added to create a branch from _develop_ named
_weekly_tests_ and moves the cases from `$HOMEgfs/ci/cases/weekly` to
`$HOMEgfs/ci/cases/pr` and then opens a PR and labels it with _CI-Hera-Ready_ and
_CI-Orion-Ready_ thus creating a weekly high resolution test run that can easily be
launched by a **cron** job.

Resolves NOAA-EMC#1663

+# Script description: Top level driver script for running
+#                     weekly CI regression tests
+#
+# Abstract:
+#
+# This script runs the high resolution cases found in $HOMEgfs/ci/cases/weekly
+# from the develop branch for the global-workflow repo that are intended to run on a weekly basis
+# from a cron job. When run it will clone and build a new branch from the EMC's global-workflow and
+# and create a pr using GitHub CLI by moving and replacing the yaml case files in
+# ${HOMEgfs}/ci/cases/weekly to {HOMEgfs}/ci/cases/pr.  Then the requisite labels are added
+# so that the current BASH CI framework can then run these cases.  Since this script
+# creates a PR with the CI-Ready labels, the BASH CI framework will automatically run these cases 
+# from that point so it is only required to run this script once from a single machine.
