support workflow run url in comments

[motatoes]

This change will also add workflow url in the summary comment that digger adds. It will fail gracefully if for whatever reason the workflow url could not be found and the user will see a blank or "#" as the link instead of the actually link. For it to work users need to add the following as one of the steps in their workflow job:

    steps:
      - name: 'Workflow ID: ${{github.event.inputs.id}}'
        run: echo run identifier ${{ inputs.id }}
