basic auth and server reflection broken with io.grpc >= 1.66.0

[profhenry]

grpc-spring compiles against io.grpc 1.63.0, but up to now it was possible to use a more recent version of io.grpc.
This works fine up to 1.65.1, but with 1.66.0 there is a incompatibility.

io.grpc added support for server reflection v1, see grpc/grpc-java#6724. They still provide support for server reflection v1alpha.
When implementing a grpc server with grpc-spring server reflection is (still) offered in version v1alpha (which is good because of backward compatibility) and this works in general. But when using in combination with spring security and basic authentication it does no longer work :-/ You always get a "PermissionDenied".

I haven't figured it out yet but i think spring security gets confused because ProtoReflectionService binds the new ProtoReflectionServiceV1 still using the v1alpha service descriptor, see here.
