[10.x] Add withQueryParameters to the HTTP client (#47297)

* Add `withQueryParameters` to the HTTP client

Some APIs require some query parameters to be always set. For example auth token (even though this isn't a great practice).

With this new helper, we can create a macro with the query parameter always set.

* Add more tests for `withQueryParameters` with arrays

See laravel/framework#47297 (comment)
