CI is failing due to critical CVE in built container images which is fixed in #73 so once that's merged we can rebase this and make sure the CI passes.

Actually, I think the changes in this PR might contradict this comment so maybe we need to think about how to set sensible defaults more carefully.

I think that means we probably just want to set the default LLM params here for the chat app only, rather than at the level of the base LLMParams python object which is shared by both the chat and image-analysis apps.

Should we do this for all params or just top_k?

I guess it probably makes sense to set all of them to chat app Azimuth defaults documented here for consistency.
