Point compose files to the deploy.yml file of tag 1.18.0

[Ekhorn]

Description

This resolves the following issue:

• Custom project: docker-compose files reference submodule that is not present anymore openremote#1620

You can check the diff between these by running the following commands.

git switch main
cp profile/dev-testing.yml profile/testing.yml # make sure openremote is a submodule (or patch the compose file appropriately)
git cherry-pick bed5426609c457cbd2389d42269a8bf452aaee56
diff <(docker compose -f profile/testing.yml config | sort) <(docker compose -f profile/dev-testing.yml config | sort)

Resulting diff

60a61
> x-base: https://github.com/openremote/openremote.git#1.18.0:profile/deploy.yml

I would say this is an intermediate solution until we have OCI artifacts to point to.
