chore(cli): explicit defaults to yargs definition and cli arguments (#…

…32596)

This makes sure we have a default value (even if its `undefined`) for every option in yargs. There is a special case for arrays where the default will be `[]`. 

I also took the liberty to simplify the eslint exemptions by changing the prettier options.
