Consider providing a non-distroless Docker image

[SoerenHenning]

With #108 automatic builds of a Docker image were introduced. The provided Docker image is a distroless one, which should be absolutely fine (and probably the best option) for running crdoc in most situations.

Unfortunately, GitLab CI/CD requires images that contain a shell. I guess similar requirements also exist in other CI/CD tools.

Hence I'm asking whether a second image could be provided which builds upon alpine or similar. I looked at the GoReleaser docs and it seems to be possible to define multiple image with different Dockerfiles.

No need for multiple images, changing the base image in the current Dockerfile should be enough. The preference would be to switch to ubi8-minimal. Is there any way for you to verify if that ubi8 works with gitlab beforehand?

Okay, great. I thought there might be some reasons why you would prefer a distroless image. I just did some small tests with registry.access.redhat.com/ubi8-minimal:latest and it seems to work perfectly fine.
