The Draupnir roles now use `community.docker.docker_image_pull` and
`community.docker.docker_image_build`, both first available in
community.docker 3.6.0 (Jan 2024, shipped with Ansible 9.2.0).

This pin only takes effect for AWX / Automation Platform users (CLI
users do not install collections from this file), but those are the
users most likely to hit the issue with a stale collection cached in
their controller.

The file is not used by the playbook's standard CLI install flow
(`make roles` / `just roles` only install roles via ansible-galaxy, not
collections). It exists for AWX / Ansible Automation Platform users,
where it is auto-detected during project sync.

Without this comment, the file looks like an unused leftover and is a
recurring source of confusion when discussing collection version pins
(should we add one here, etc.). Documenting the actual audience makes
those decisions more obvious.

No functional change.

Use correct collection for docker commands

Correct collections name

Add collections for simple awx compatiblity
