[Ransomware live] Create relationships with the wrong sectors

[Lhorus6]

Description

The Ransomware live connector is incorrectly fetching sectors, which makes relationships with the wrong entities. The problem is in this query: https://github.com/OpenCTI-Platform/connectors/blob/881e881c79865291945f8ca1ffc3bdee0dcf1bee/external-import/ransomwarelive/src/lib/ransom_conn.py#L291C7-L292C7

The "search" operator is used instead of "eq". This produces this kind of problem:

If I have the sector "Food and drinks businesses" in my platform and I search with this filter for the sector "Business Services", I can get as a result of my query the sector "Food and drinks businesses" even if I have "Business Services" in my platform.

To make sure to fetch the right sector, the "search" operator should be replaced by "eq".

However, rather than searching for an existing sector, the connector should only create a sector (create the stix object) without worrying about what exists in the platform. This is how the connectors should work.

Environment

OCTI 6.5.3

Reproducible Steps

Steps to create the smallest reproducible scenario:

1. Ingest the sectors using the OpenCTI dataset connector
2. Enable the Ransomware live connector
3. Review the relationship done by the connector and compare to the relationship that should normally have been made (example with "Food and drinks businesses" vs "Business Services")
