### Proposed changes

<!--Give us a brief description of what you've done and what it solves.
-->

Upgrade google-protobuf from 3.21.2 inherited from @pulumi/pulumi to
3.21.4 (the latest version). This affects both the provider and the Node
SDK that are coupled together in this provider.

Fixes spontaneous failure of TestAccAwsCluster and many other tests.
Typical failure:
