Bazel: Remove unused commons-lang3

After removing Elasticsearch and Jest REST client library, commons lang3
is not used any more in Gerrit core. Given that we have forgotten to
remove it and stil expose it in plugin API only confused the plugins
that depend on it, because the build pass, but then the plugin cannot
work, because the required dependency is missing.
