Update Ansible configuration to integrate SOPS for managing secrets. Enhance README.md with SOPS usage instructions and prerequisites. Remove External Secrets Operator references and related configurations from the bootstrap process, streamlining the deployment. Adjust playbooks and roles to apply SOPS-encrypted secrets automatically, improving security and clarity in secret management.
