Create job to update OSCAL component for BigBang

Existing OSCAL component for BigBang has not been updated for 3 months. It would be good to introduce some automation to keep it fresh as the sub-components are updated.

Existing OSCAL Component:

• https://repo1.dso.mil/platform-one/big-bang/bigbang/-/blob/master/oscal-component.yaml

Tool used previously to generate OSCAL component for BigBang
