chore(test-data): narrowly introspect scalar types

[jaikamat]

Summary

This PR edits the codegen config file to prefer more specific types rather than unknown for scalar values.

This work was prompted by a lack of backwards compatibility from the new changes to test-data fixtures with respect to the B2B sample import, in which unknown values could not be assigned to more narrow preset-defined types like string.

Since scalar types are now inferred more narrowly, the test-data fixture types and those same types introspected in mc-services should be identical and compatible.

Merging this in and cutting a new version will allow us to make more streamlined changes in mc-services to update the B2B feature.
