Fix doctest data

[Yury-Fridlyand]

Description

Clean up doctest test data. Fortunately, no test failed due to incorrect import.
Doctest uses python client to manipulate with test data and it interpreted {"index":{"_id":"0"}} as a doc to import. Fortunately, opensearch DSL ignores such docs for queries being tested, so it didn't affect the test.

It's very odd how this was missed. Also very odd that doctests don't use the bulk endpoint.
