API derivation broken in Scala 3.7

[WojciechMazur]

Issue spotted in Scala 3 Open Community Build - build logs
API derivation used unsafe access to newClass from Quotes API using reflection. This call is now broken in Scala 3.7. The experimental method signature has changes and is now taking additional arguments, see scala/scala3#21880 for details

Thanks, I was wondering when it'd break 😄 that's what I get for trying so hard not to use @experimental.
