Hello!
I quickly checked few versions, at least it should be > 2.1
Maybe I'm wrong somewhere
But I think just in case it's necessary to add tests of other versions specifically for ML

I tried to set up a 1.3 OpenSearch cluster and run the test, and it seems that the tests for train, predict, train and predict APIs passed.

Great, I apologize for my excessive OCD. I was also trying OS 1.3 with Docker Compose, which we have in the ML folder, and it wouldn't start on these versions, so I thought there might be an error here. Most likely, in the future, if we introduce 1.3 and test on them, we will have to redo the Docker Compose we have there now

No problem at all! I I referenced the Docker Compose from here, which potentially more accurate :)
