Downloading private leaderboard

When using `kaggle competitions leaderboard playground-series-s4e4 --show` we can change the `_override_public` value to get the public leaderboard. Otherwise by default it's the private leaderboard (if available). So `--show` allows to get the public or private leaderboard depending on the availability of the private leaderboard and the value of `_override_public`.

Could this be the same with `--download`?

Also it seems a bit misleading that the default of `--show` and `--download` is not the same depending on the availability of the private leaderboard.
