start: deploy model from registry

### Report

We have the [sagemaker example](https://github.com/iterative/example-repos-dev/blob/master/example-get-started-experiments/code/.github/workflows/deploy-model.yml) where we deploy, but we don't expose the endpoint nor provide a way for the user to try deployment themselves.

Some options to explore (we could also try to partner with whoever we choose here):
- could start with just building a docker image and pushing it to dockerhub
- https://github.com/replicate/cog with or without hosting on https://replicate.com/
- flyio like in https://iterative.ai/blog/mlem-nanogpt-modal-flyio
