Clarify what docker-compose versions are actually supported

[fabiobrz]

Issue Overview

Since:

• Arquillian Cube includes functional support and integration tests for docker compose v1 and v2, but v1 has been deprecated
• The current guide states that docker-compose v1 is the only supported by the CUBE format

We should:

• evaluate whther docker-compose v1 related removals in Remove the deprecated things and replace Fabric8 Maven plugin with JKube maven plugin #1309 could impact this issue
• investigate whether anything is missing in the CUBE format implementation in order to support docker-compose v2
• investigate whether anything alse is missing on the functional/test side to state that docker-compose v2 is supported
• Implement any potential changes that would follow up by the previous investigation activities
• Evaluate whether v1 support can be dropped right away or in the next minor
• Perform related updates to the documentation
