Subject: [PATCH 2/2] fix: Use Python3_EXECUTABLE for the gRPC Python codegen

cd84eea switched the lookup to find_package(Python3 ...) but left the
custom command on ${Python_EXECUTABLE}, which that package never
populates. The variable expands to empty, so the grpc_tools.protoc
command runs with no interpreter and grpc-service-py-library cannot
generate its output.

TRITON_COMMON_ENABLE_PROTOBUF_PYTHON defaults to ON, so this is on the
default build path rather than an opt-in one.

Only Interpreter is requested, which is all the codegen needs.
