fix(js-api): fix the generated types for rule domains

[dyc3]

Summary

This fixes the generated type for domains in the linter configuration. Now, that type gets emitted is Record<RuleDomain, RuleDomainValue>.

I've tested this on the website repo, and actually both an object and a Map work. I picked Record here since building Maps tends to be a little unergonomic.
