Update BB base to 2.0.0

The current BB base image causes issues for us due to constantly updating utilities. We are now going to provide the capabilities for each of the main uses separately:

• big-bang/utilities: Provides full range of utilities for use in airgap
• big-bang/base: Provides curl, kubectl, yq, jq for use in BB jobs

This ticket should include 3 main tasks:

• Finishing the refactor to the IB image, ensuring it gets updated to 2.0.0 - dsop/big-bang/base#22 (closed)
• Updating ALL references to the BB base image to 2.0.0 (multiple packages)
• Updating renovate files as needed to ensure we are tracking the BB base image properly for future updates
