pymongo instrumentation: Invalid COLLECTION_METHODS_V3 names

[lancetarn]

The pymongo instrumentation generates some harmless-but-noisy logs for versions 3.0.0 - 4.5. There are several method names that get added to the methods we assume will be on pymongo Collections that are not valid until at least version 4.5 AFAICT. It is possible that they existed earlier and were removed for a stretch of releases.

    "drop_search_index",
    "create_search_indexes",
    "create_search_index",
    "list_search_indexes",
    "update_search_index",

These should be removed from pymongo < 4.5 instrumentation attempts.

Example log record:
