consider moving the docker related repos into a own org

Our current State showed us that it could lead to massiv delays if we do not get more maintainers with more access rights so we need a Org to handle that permissions at present https://github.com/sameersbn is a user that is total fine i created 2 Orgs that could act as new org or home for this images so that we can scale the Contributors

• https://github.com/orgs/sameersbn-docker
• https://github.com/orgs/dockerimages

i already added all users as admin to both orgs so we can start switching.

so we only need to choose where we fork merge and then we simply soft switch over the users incremental i can write a complet migration and deprecation plan for the transition at the end github will link directly to the new org and repo if the old gets requestd

Closes: https://github.com/sameersbn/docker-redmine/issues/474 as it got cluttered.
