code-gen(docs): do more with `.docs()`

[dirkdev98]

• [x] Validate single line and multiline usage on all places where it is printed + print consistently
• [x] Print property docs in the type generator, supporting both single + multiline (Done in experimental generators)
• [ ] Support {@reference UniqueName} replacements.
  • If UniqueName is a route, resolve to apiUniqueName execept when in the router or reactQuery generator
  • Else resolve to the type
  • Use JSDoc {@link }
