fix: update compose submodule for s6-overlay entrypoint crash fix

Updates the compose submodule to commit f4dd57f on branch
fix/hermes-s6-overlay-entrypoint-crash, which:

- Removes the broken entrypoint override (bash->tini->entrypoint.sh)
- Bakes start-hermes.sh into the image as the new CMD
- Uses the image default ENTRYPOINT (s6-overlay /init)

Fixes the SIGTERM restart loop on the Hermes container.

See compose PR #56 for details.
