Overview

Remove the nonClusteredConfigTransactions flag from multiversion test suite configurations. This flag is set on jsTestOptions and the ReplSetTest code that processes this flag was removed in SERVER-84073 (ticket still open as of May 2026).

Background

The nonClusteredConfigTransactions flag was used in multiversion test suites to force config server transactions to use non-clustered collections during mixed-version testing. Now that the flag is no longer relevant, it should be cleaned up from the test configurations.
