fix(ATL-7315): Replace docker library for tests

[EzequielPostan]

This PR replaces the old docker-it-scala library with test-containers library, fixing the incompatibility issues with docker server 26.1.3

This PR adds the dependency on the testcontainers-scala library under MIT license (see https://github.com/testcontainers/testcontainers-scala?tab=MIT-1-ov-file#readme)

It also removes the dependencies on docker-it-scala, which was dependent on spotify's docker client library that was the root of the CI issue
