With this change we add a Yargs middleware that normalizes non Array options when the argument has been provided multiple times. By default, when an option is non array and it is provided multiple times in the command line, yargs will not override it's value but instead it will be changed to an array unless `duplicate-arguments-array` is disabled. But this option also have an effect on real array options which isn't desired. See: yargs/yargs-parser#163 (comment) Closes #22956
