oauth2 2.0 changed the default auth_scheme from :request_body to :basic_auth. This causes credentials to be sent in the Authorization header instead of the request body. Explicitly set auth_scheme: :request_body to maintain backward compatibility with existing integrations and VCR cassettes. Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>

This breaking change affects all apps using this gem when upgrading to oauth2 2.x. Without this fix, existing VCR cassettes and integrations expecting credentials in the request body will fail.
