`libReplacement: true` lookup folder should be configurable (via `typeRoots` ?)

🔎 Search Terms

When libReplacement: true is used, for example

  "libReplacement": true,
  "lib": ["dom", "esnext"],

It is currently not possible to instruct the TS compiler to look for @typescript/lib-dom/ in a custom folder, which makes it impossible to leverage libReplacement: true in setups where the folder does not reside in the parent chain (real-world scenario in the Chromium repository). For example adding something as follows has no effect.

   "typeRoots": [
      "./some/sibling/folder/node_modules/@typescript",         <-- Does not work
      "./some/sibling/folder/node_modules/@typescript/lib-dom"  <-- Does not work either
   ],

Pasting --traceResolution output for reference.

======== Module name '@typescript/lib-dom' was not resolved. ========

Or if typeRoots is not the right way, there should be some way to customize where to look.

Let me know if you think a minimal repro is needed. Skipping for now as the above setup seems easy to reproduce.

🕗 Version & Regression Information

Reproducing on v 6.0.2. Did not try previous versions.

🙁 Actual behavior

No way exists to tell tsc where to locate the @typescript/lib-dom/ folder.

🙂 Expected behavior

There should be a way tell tsc where to locate the @typescript/lib-dom/ folder, similar to how this is done with typeRoots for types listed in types.

Comienza reproduciendo la configuración con libReplacement, typeRoots y --traceResolution; después, sigue cómo tsc resuelve @typescript/lib-dom. Compara la búsqueda con el comportamiento de typeRoots y define una ruta de configuración que funcione para carpetas hermanas; se considerará terminado cuando la ubicación personalizada se resuelva de forma fiable y la cobertura de regresión lo verifique.
