Use driver from gRPC core 1.62.1 (#390)

* Update bazel build image for the driver

This is the same image used in #388. It upgrades bazel from 6.1.2 to
6.4.0, which is the default supported version starting with v1.60.0.

Without this change, building the driver image fails with:

/tmp/build_output/5e0c6d2c26e81c9358486406038ccc44/external/com_google_protobuf/upb_generator/BUILD:266:21:
@com_google_protobuf//upb_generator:protoc-gen-upb_toolchain: no such attribute 'output_files' in 'proto_lang_toolchain' rule

* Use the latest released driver, from grpc/grpc 1.62.1.
