Summary

I'm trying to run api-extractor on a repository with TypeScript 5.3 as a dev dependency. It was previously working with TypeScript 5.2.

Repro steps

See typescript-eslint/typescript-eslint#7821:

1. Check out that PR branch & commit
2. yarn
3. yarn build (specifically, the packages/ast-spec task)

Expected result: Successful API extraction / build?

Actual result:

packages/ast-spec $ yarn build

api-extractor 7.38.0  - https://api-extractor.com/

Using configuration from ./api-extractor.json
Analysis will use the bundled TypeScript version 5.3.0-beta

ERROR: ts.getResolvedModule is not a function

packages/ast-spec $

Details

I'm guessing this is because of the (ts as any).getResolvedModule used to access TypeScript compiler internals:

microsoft/TypeScript#55790 removed that internal API.
