TypeScript bindings enhancements

[mdekrey]

On the UI side, we'd like to attach our code generators to TanStack Query. This will be served better by a few enhancements to the TypeScript output:

• Include "method" in the conversion object
• Expand RequestConversion<> to include more meta details, including method.
• Consider splitting operations by request body type (organizing by folder?) so that the content type does not need to be included
  • Consider including request content type in the conversion object
  • If operations are split, consider moving response parsing to separate file for reuse
  • If operations are split, provide additional files like operations/index.ts that include support by request type
• Consider moving TS dependencies into generated output instead of the shared library for better side-by-side support of other versions of the generator Moved to TypeScript shared type packaging #126.
