extends clause in tsconfig should look into the exports field

[ilogico]

TypeScript 5.0 now looks into the exports field of package.json when resolving the extended files, but esbuild doesn't appear to do so.
Example:

{
  "extends": "@whatever/tsconfig/node"
}

{
  "name": "@whatever/tsconfig",
  "exports": {
    "./node": "./tsconfig.node.json"
  }
}

will emit this warning:

▲ [WARNING] Cannot find base config file "@whatever/tsconfig/node" [tsconfig.json]

    tsconfig.json:2:13:
      2 │   "extends": "@whatever/tsconfig/node",
