Consider providing a Docker image

[SoerenHenning]

To run crdoc as part of CI pipelines, it would be helpful to have a Docker/OCI image provided with crdoc installed. While of course everybody could simply create such an image on their own, having an official image, which is kept up-to-date by the maintainers, is a more "reliable" solution.

Do the maintainers think providing such an image is possible, for example, via GitHub Container Registry?

Thank you very much for providing a Docker image. While this image allows our developers to build the CRD docs locally without installing crdoc, it is unfortunately not possible to use this image in Gitlab CI as those images must contain a shell. I opened #109 as a follow-up to ask whether such an image could be provided in addition.
