fox(providers): Downgrade requested OAuth scope of TikTok provider (#12608)

* Downgrade requested OAuth scope of TikTok provider

The provider is currently requesting a token with `user.info.profile` scope, which is more restrictive than `user.info.basic`. The latter is the one provided by default by the TikTok Login kit and as such, should be the one used for authentication purposes with TikTok. The user info requested by the provider is also covered by the `user.info.basic` scope. For this reason, this PR changes the requested scope to `user.info.basic`.

* Update tiktok.ts

Do not request user_name
