We need to create a production image for the revscoring topic model server that can be hosted in the WMF Docker registry.

This should be a blubber.yaml file that lives in the ./pipeline/topic directory. It should target the revscoring/topic directory and copy the model-server/ directory.

This has already been done for editquality (see: T279004) which can be used as an example.

Side note: It may also be helpful in defining a 'test' variant that can run linting/formatting tools that can be used in the deployment pipeline.
