## Description of the problem, including code/CLI snippet As per the [documentation](https://github.com/python-gitlab/python-gitlab#using-the-docker-images) docker images are pushed to the GitLab container registry. However, the [gitlab container registry of this project](https://gitlab.com/python-gitlab/python-gitlab/container_registry/592152)'s latest container image for registry.gitlab.com/python-gitlab/python-gitlab is version v5.6.0 while the py package's current version is [v8.3.0](https://github.com/python-gitlab/python-gitlab/releases/tag/v8.3.0). ## Expected Behavior All releases produce a container image that is pushed to https://gitlab.com/python-gitlab/python-gitlab/container_registry/592152 ## Actual Behavior Since version v5.6.0 no further release was pushed as a container image to https://gitlab.com/python-gitlab/python-gitlab/container_registry/592152
