Add support for docker container

[baywet]

We can probably just steal and adapt the dockerfile definition from kiota
https://github.com/microsoft/kiota/blob/d064cb98b92f9b1e20e988b519eb8093ce762f48/Dockerfile#L1

And then steal the build/publish steps from the ADO pipeline

https://github.com/microsoft/kiota/blob/d064cb98b92f9b1e20e988b519eb8093ce762f48/.azure-pipelines/ci-build.yml#L1004

And adapt it to publish to the GitHub package container
