Sentry Admin Script always fail because of missing import of lib script.
### Legal Boilerplate
Look, I get it. The entity doing business as "Sentry" was incorporated in the State of Delaware in 2015 as Functional Software, Inc. and is gonna need some rights from me in order to utilize my contributions in this here PR. So here's the deal: I retain all rights, title and interest in and to my contributions, and by keeping this boilerplate intact I confirm that Sentry can use, modify, copy, and redistribute my contributions, under Sentry's choice of terms.
With #3595, we now check both `docker-compose` and `docker compose` versions so this patch removes the implicit fallback to `docker-compose` for `$dc_base` and makes it explicit.
In this version, there's a new `--pull` argument for `docker compose run` which we will start leveraging, especially with `sentry-admin` command.
Should come with a slight speed boost.
