/examples/nvexec/bulk.cpp using nvexec::multi_gpu_stream_context?

Hello,

I've been messing around with the library examples and noted that the /examples/nvexec/bulk.cpp does not compile when using nvexec::multi_gpu_stream_context. What is the "canonical" way to send a bulk job to a multi-gpu context?

I'm writting a multi-agent simulator, and currently I'm using:

    const auto work2 = stdexec::when_all(
      stdexec::just() |
        exec::on(gpu, stdexec::bulk(environment->size, human_mosquito_contact)),
      stdexec::just() |
        exec::on(gpu,
                 stdexec::bulk(environment->size, mosquito_mosquito_contact)));
    
	stdexec::sync_wait(std::move(work2));

Start with /examples/nvexec/bulk.cpp and reproduce the compilation failure using nvexec::multi_gpu_stream_context. Inspect the example's bulk and multi-GPU context usage, then verify that the canonical multi-GPU bulk-job pattern compiles and runs successfully.
