CI Scripts for high resolution weekly cases

[TerrenceMcGuinness-NOAA]

Description

A Python 3 script using PyGitHub 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 simply have been launched by a cron job.

Resolves #1663

PS: A bash version that does not use PyGitHub or GitHu CLI is also included if needed on platform that has neither.

Type of change

• New feature (adds functionality)
• Maintenance (new CI test)

How has this been tested?
