Walkthrough

This PR updates the set of kernel modules that are blacklisted (prevented from loading) in Linux stemcells. The apply.sh script replaces three module blacklist entries—esp4, esp6, and rxrpc—with three new ones: rds, floppy, and algif_aead. Corresponding test assertions in the shared examples file are removed to reflect the updated blacklist configuration.
