Uncollapse single-use defs

[ProbablePrime]

The latest version of our schemas, for some reason splits even objects that are only used once, into their own def location within the schema.

Here's an example where a single value is for some reason converted to a separate def. https://github.com/Yellow-Dog-Man/JSONSchemas/blob/main/schemas/AppConfig.schema.json#L151-L153

It makes sense to do this with common values, such as enums, but for basic values like string. It shouldn't be doing this.
