Missing allow_partial_search_results type in openPointInTime API

[vitaliidm]

🐛 Missing type

In Version 8.16 it is not documented support of allow_partial_search_results parameter, which is available in API.
But when I pass it in method, despite type error, it works

    await services.scopedClusterClient.asCurrentUser.openPointInTime({
      index: threatIndex,
      keep_alive: '5m',
      allow_partial_search_results: true,
    });

It looks like this type is missing in specs
