Restore grpcio pin for python 3.10 (#11784)

Summary:
Hangs in python 3.10 in grpc seem to be happening after all - it's
possible they are a bit more rare, but they definitely happen:
https://buildkite.com/dagster/dagster/builds/46036#0185c6be-2c65-4ea7-b368-3c80a933f7bc

so for now we need to bring back the pin for all versions I think.
