Update WORKSPACE in Bazel example

v2.3.4 is not available

2.3.4 hasn't been released yet, but this is about 2.3.4-SNAPSHOT.
The problem here actually is that error_prone_ant no longer exists. AFAICT, it's been replaced with error_prone_core's with-dependencies variant (along with a few unbundled dependencies, due to license concerns)

@tbroyer
Thanks for the reply.
I actually first tried "error_prone_core-with-dependencies-2.3.4-SNAPSHOT"
But I was not able to find artifact-name for the same.
Can you provide the artifact-name that I can use for the "error_prone_core-with-dependencies-2.3.4-SNAPSHOT"?
Thanks.

Try with com.google.errorprone:error_prone_core:jar:with-dependencies:2.3.4-SNAPSHOT, or possibly com.google.errorprone:error_prone_core:2.3.4-SNAPSHOT:jar:with-dependencies.

That being said, it looks like this would eventually have to be moved to using the Skylark jvm_maven_import_external (see https://docs.bazel.build/versions/master/skylark/backward-compatibility.html#remove-native-maven-jar or bazelbuild/bazel#6799)
