[TRACKING] Release of TRPC Client Generator

[polvallverdu]

I've created this issue to track what needs to be done to release the TRPC client generator

• quicktype doesn't allow to personalize nested types (wosherco/quicktype@6f5bb27)
• JSON Serializable not generating (.g.dart files), which prevents serialization and dezerialization ([FEATURE]: On Dart with Freezed, be able to prevent conflicts with nested types on JSON Schema glideapps/quicktype#2660)
• Models and Routes generators are not matching the class names for inputs and outputs (No issue)
• Routes generator puts wrong path for queries (No issue)
• Add transformers support (wosherco/trpc-extractor@6f3ca2f) (No issue)

I think I'm not missing anything...
