chore(compass-collection): ignore mongoType from LLM response CLOUDP-351514

[kpamaran]

Description

Remove usage of the mongoType field from the LLM response supporting mock data generation. mongType is will still be fed as context to the LLM, but the LLM does not need to return it back. There is less data subject to AI hallucination and ~15-20 tokens per field are saved because of this. A separate PR will update the backend response

Note: This feature is in development behind an experiment flag. Normally, if the feature was already rolled out we would version the API change.

Assigned mabaasit for team compass-developers because Anemy is out of office.

Note that malformed fieldPaths will be stripped anyway, see below. Might make sense to just not bother storing such cases here, or make the behvior clear in the comment.

I removed the 'String' fallback and updated the comment to note validateFakerSchema 👍🏼

Nice work, one small comment
