feat(devservices): use distroless image in devservices

[oioki]

This PR will switch the snuba container in sentry devservices to the "distroless" version.

$ docker ps -f "name=snuba-snuba-1"
CONTAINER ID   IMAGE                                        COMMAND                  CREATED          STATUS                    PORTS                                NAMES
e487314c8b09   ghcr.io/getsentry/snuba:nightly-distroless   "python3 /usr/src/sn…"   17 minutes ago   Up 17 minutes (healthy)   127.0.0.1:1218-1219->1218-1219/tcp   snuba-snuba-1

This was previously smoke tested in #7829 on my machine. New events are being ingested and retrieved on sentry devserver.

Also removing honcho package, replacing it with native subprocess library, to avoid spawning the missing shell (more detailed explanation in https://github.com/getsentry/sentry-analytics/pull/26)
