[Metricbeat][parity-tests] Missing some newly added ES fields

[igoristic]

ES parity test failed using the following ES snapshot: https://snapshots.elastic.co/8.0.0-2ce56a76 with errors:

10:05:28 ERROR: Metricbeat-indexed doc for type='indices_stats' has unexpected deletion: indices_stats._all.total.bulk
10:05:28 ERROR: Metricbeat-indexed doc for type='indices_stats' has unexpected deletion: indices_stats._all.primaries.bulk
10:05:28 ERROR: Metricbeat-indexed doc for type='node_stats' has unexpected deletion: node_stats.indices.bulk
10:05:28 ERROR: Metricbeat-indexed doc for type='index_stats' has unexpected deletion: index_stats.total.bulk
10:05:28 ERROR: Metricbeat-indexed doc for type='index_stats' has unexpected deletion: index_stats.primaries.bulk

I think these fields were added in the ES pr here: elastic/elasticsearch#52208

As far as I can tell it doesn't break anything in master, but still worth checking/fixing
