Update Buildifier to 0.22.0
I'm seeing some weird errors while testing formatting support (https://buildkite.com/bazel/bazel-bazel-github-presubmit/builds/1916#1a0b4746-ced0-472c-8ac1-19bf4b6c09e8) and cannot reproduce them locally with the latest Buildifier version 0.22.0.
CI has been using 0.20.0, which might be an explanation. Irregardless of this specific issue using the latest version is a good idea.
