Use the canonical images created in BUILD-895 and deploy them for public/internal use.

Open questions / TODO's

• 6.3 only or 6.2 as well?
  • do both to get some experience before 6.3 comes out
• is it fine that dx-core becomes publicly available?
  • it's already available on files.magnolia-cms.com. Fine with Jan
• SNAPSHOTs or releases exclusively?
  • releases go to DockerHub
  • SNAPSHOTs to ECR, so that they can replace the CLI for say some documentation team member who needs to make the instance run locally
• gain clarity on accounts/strategy in https://www.notion.so/magnoliacms/Docker-Hub-presence-674f8220292849ca9cf579057a8bfbf4
• use these images for nightly, for tests & other places where we currently use SNAPSHOTs
• impact on docs where the CLI is used for educational purposes
  • keep the CLI but make it rely on Docker?
  • or tell people to use Docker and keep the CLI's file manipulations in a volume?
  • probably setup a call with Jaroslav, Topher, Martin, Alex, Martina Michlova
• showcase how to use configuration profiles via environment variables
• the images need to be multi-platform right away, supporting both ARM (MacBooks) & AMD CPU architectures
