chore(ci): make helper integration tests runnable

[Haroenv]

Summary

Since a while, we haven't run the helper integration tests, and thus we haven't noticed that they don't pass on v5 anymore

Result

integration tests pass on v5 again

todo once this is passed, make sure we send the INTEGRATION_TEST_API_KEY and INTEGRATION_TEST_APPID env variables

Seems like it's going into the search client v4 branch although I am using a v5 client. Any idea?

[Haroenv]

ah didn't think of that, it's probably because it has initIndex for the integration parts now. I'll see how that can be improved.
