TF Compare Script: Refactor logic to pull in current Runtime Version

[sihammill]

Description

Issue

Currently the runtime version isn't passed through the jobs in the pipeline and this is something we need as the RT version is added to the bug reports when they are created and when the comments are automatically updated.
This basic bit of information is vital for the devs to see what RT is affected.

Current workaround

As it stands, the only real way to get the RT version is to download the logs for the current workflow run which includes the version, we then extract the version and save it to a variable. It's not pretty but it works (well not now).

Proposal

Look through the pipeline code and see if there is a way we can get the current RT version more reliably, maybe get it form the config file that is passed in to the pipeline, also maybe use the logs as a fall back. way of extracting the RT version.

Update

a GitHub variable has been setup for the Runtime Version: ${{ github.event.inputs.RUNTIME_VERSION }}

Adding this as a parameter to the command line in the workflow files that calls the tf_compare.py file would mean the parameter can then be accessed within the python file using:

parser = argparse.ArgumentParser(description="GitHub Artifact Processor")
parser.add_argument('--rt', type=str, required=True, help="Current Runtime Version")
args = parser.parse_args()
RTVersion = args.rt

The updated command line for the workflow file would be:

python .\tf_compare.py --github-token ${{ [secrets.GH](http://secrets.gh/)_PERSONAL_ACCESS_TOKEN }} --workflow ${{ github.workflow }}.yml --rt ${{ github.event.inputs.RUNTIME_VERSION }}
