fix: typescript-config export form react-native-web (#10671)

### Description

<!--
  ✍️ Write a short summary of your work.
  If necessary, include relevant screenshots.
-->
When setting up the react native web template, you get hit with `File
'@repo/typescript-config/nextjs.json' not found.` in
`apps/web/tsconfig..json`.

Properly exporting the config files from `packages/typescript-config` so
it works out the box.

### Testing Instructions

<!--
  Give a quick description of steps to test your changes.
-->
Clone the template, notice no more `no found` errors.
