TypeScript 7 (TS-Go) support

This is the tracking issue for support for TypeScript's port to Go.

Updating to TypeScript 7 is unfortunately not an easy change for TypeDoc as:

1. The TypeScript 7 API is a complete rewrite from the TypeScript 6 and prior APIs.
2. TypeDoc heavily depends on some internal features in TypeScript 6 which are not present in the TypeScript 7 API.

The plan today is to perform a feature freeze once TypeScript 7.0 has released. At that time, additional feature requests will be put on hold until after the necessary changes to support TypeScript 7 have been made. Bug fixes will likely also be limited to critical issues.

There is no timeline for how long this will take. I work on TypeDoc during my free time during the weekends, usually an hour or two per week. If your company has a pressing need for TypeDoc to support TypeScript 7 and would like to sponsor faster development, please reach out.
