Bug Report

Adding a common "typeRoots" key on an extended configuration is not taking into account anymore. We discussed it a little bit on this PR: #51715

🕗 Version & Regression Information

it used to work on the v 5.0.4 but it stopped working when I migrted to 5.1.3.

🙁 Actual behavior

I have a global tsconfig json file as following:

// base.json
{
  "$schema": "https://json.schemastore.org/tsconfig",
  "compilerOptions": {
    "typeRoots": ["../../node_modules/@types"]
  }
}

And I'm using it within my monorepo on each package as following:

{
  "extends": "@slowy/config/tsconfig/base.json",
  "compilerOptions": {
    "typeRoots": [ "../../node_modules/@types"]
  },
}

However as you can see, I have to re-declare the typeRoots option which was not necessary before the library update.

🙂 Expected behavior

Being able to extend the typeRoots configuration.

Thanks!
