Add typesVersion for resolving all types using legacy moduleResolution

When TS is set up to not use a `moduleResolution` of `node16` or `bundler` yet (like legacy `node`/`node10`), then TS would not look into `exports`.

There is `types`, but that only works when resolving the main index module, like `import from 'ember-cli-page-object'`, but all other submodules like `ember-cli-page-object/adapter` would fail to resolve to `types.d.ts`. 

This is removing `types` in favor of `typesVersions`, supporting the same wildcard-matching that `exports` does.
