Bump to com.google.protobuf:protobuf-java:4.28.2

Part of bazelbuild#1482.

Bumps every Scala version up to use protobuf-java:4.28.2, to
preemptively avoid the following error produced by upcoming Scalafmt
updates:

```txt
$ bazel test --repo_env=SCALA_VERSION=2.11.12 //test/scalafmt/...

INFO: Analyzed 9 targets (80 packages loaded, 3307 targets configured).
ERROR: .../test/scalafmt/BUILD:43:20: ScalaFmt

  failed: Worker process did not return a WorkResponse:

Exception in thread "main" java.lang.NoSuchMethodError:

  [ ...snip... ]
```

This issue seemed to suggest a library bump may fix it, and it did:

- protocolbuffers/protobuf#9236

Fortunately, even though this is a major version bump from 3.10.0 to
4.28.2, there were no compatibility issues, per:

> Protobuf major version releases may also be backwards-compatible with
> the last release of the previous major version. See the release notice
> for more details.
