Description
Minimal update to gpu allocator 0.22.

Testing
Tested water, shadow, and compute example. Also ran cargo nextest and everything (except the zero_init_workgroup_mem test that was already broken) passed.

We could potentially use gpu-allocator's new allocator.create_resource(...) function, but I'm not sure what the benefit of using it over what we're already doing would be.
