gha-ci: fix builds from cache: add ~/.cache/bazel (+ update actions)

fixes https://github.com/golang/protobuf/issues/1562

Update to the latest version of the actions we use while we’re at it.
For setup-go@v4 this means we get caching based on go.{mod,sum}.
For actions/cache@v3 this means we get zstd compression.
