update rabbitmq docker containers to v3.12.0 (#2359)

# What this PR does

Update `rabbitmq` Docker containers used in the `docker-compose` config
files, Drone pipelines, and GitHub Actions to use version 3.12.0.

FWIW, we're already using v12.0.0 of the bitnami `rabbitmq` `helm` chart
which, by default, uses the `3.12.0-debian-11-r0` tag for the `rabbitmq`
image ([chart
docs](https://artifacthub.io/packages/helm/bitnami/rabbitmq/12.0.0)).

closes #695
