fix(types): expose public interfaces from root index.d.ts

[Hotell]

this tweaks #788 by exposing proper public types API from root index.d.ts so consumer doesn't have to traverse private package path to access interfaces.

before

// @ts-check
const tsLoaderOptionsRules = /** @type {import('ts-loader/dist/types/interfaces').LoaderOptions}*/ ({
  configFile: tsConfig,
  transpileOnly: true
})

after

// @ts-check
const tsLoaderOptionsRules = /** @type {import('ts-loader').Options}*/ ({
  configFile: tsConfig,
  transpileOnly: true
})
