Pull request overview

This PR removes the legacy config-bp.json Cardano node configuration handling for signer block producers, aligning the infrastructure with supported Cardano node versions (10.7+) and unblocking deployments on 11.1 by relying on the standard config.json.

Changes:

• Removed Terraform provisioning steps that created and maintained config-bp.json for signer Cardano block producers.
• Updated the signer block-producer docker-compose override to start cardano-node with /config/cardano-node/config.json instead of /config/cardano-node/config-bp.json.
• Bumped the infra version from 0.5.21 to 0.5.22.
