[#1035] Bump cardano-node and cardano dbsync

Updated the Makefile and docker-compose file to bump the cardano-node
and cardano dbsync versions to 8.11.0-sancho and sancho-4-3-0-docker
respectively. These changes align with the user story's requirement to
bump cardano-node to version 8.11.0 and to ensure the infrastructure
configuration is updated accordingly.
