add support for `provider_query_params` option on getAuthorizationUrl (#1308)

## Description
- moves to using `qs` to create query strings for `getAuthorizationUrl`
to more easily support a new object type parameter and stringify it into
the format our API expects
- we have lots of tests for `getAuthorizationUrl` (sso and
user_management) that compare full url strings to snapshots, so the fact
that all of these tests still pass (with `qs` options set to maintain
backwards compatibility with our previous implementation) makes this
feel pretty safe to me, but if anyone disagrees, let me know
- adds support for the new `provider_query_params` query parameter /
option added in https://github.com/workos/workos/pull/41556
