extends in tsconfig.json should prefer tsconfig.json over package.json

[JounQin]

Describe the bug

// lib/tsconfig.json
{
  "extends": "..", // it means `../tsconfig.json` actually, but `../package.json#main` is resolved unexpectedly
  "compilerOptions": {
    "rootDir": ".",
    "outDir": "../lib"
  }
}

// tsconfig.json
{
  "extends": "@1stg/tsconfig/node16"
}

// package.json
{
  "main": "lib/index.cjs"
}
