Fix failure deprecated_wire_ops_mongos.js with v5.0 windows debug build

This failure occurs due to timeout. In SERVER-58372, I've already increased timeout to 5 times but still we're seeing this failure. I don't think we can rely on that the increased timeout will robustify this test on v5.0 windows debug build. So, will try to minimize the execution time using writeConcern setting and will see how it plays out.
