[fix](test) run search score TopN case in nonConcurrent group

What problem does this PR solve?

Issue Number: N/A

Related PR: #67363 (same fix on branch-4.1), #67327 (backported the suite to branch-4.1), #65821 (introduced the suite on master)

Problem Summary:

test_search_score_topn_predicates (added on master by #65821) runs in the shared concurrent P0 group. On branch-4.1 it fails intermittently on its very first query, right after CREATE TABLE + INSERT + sync, with:

errCode = 2, detailMessage = [INTERNAL_ERROR]SearchExpr should not be executed without inverted index

This was observed on branch-4.1 CI (2 failures out of 4 runs) and fixed there by #67363, which moves the case into the nonConcurrent group. master carries the identical suite grouping ("p0"), so it is exposed to the same intermittent failure when the case races other P0 cases. This PR applies the same one-line fix to master to keep it out of the concurrent group.
