Sharded createSearchIndexes does not return per-shard index IDs in its response. This prevents by-ID search index operations (update, drop, list) from being tested in e2e suites against a real mongot.

by-ID tests in jstests/with_mongot/search_mocked/text_search_index_commands.js remain mocked because index IDs are not reliably available after creating a search index on a sharded collection. See jstests/libs/query_integration_search/search.js ln#224 for the current helper limitation.
