dotnet nuget push *.nupkg --config-file switch appears to be missing. nuget.exe push has it.

customer reported the following issue - https://github.com/dotnet/docs/issues/6729

In documented examples, --config-file is provided as a way to specify a custom config file. However, this switch is not part of the synopsis, and gives an error if used

Once this is fixed, please let us know, so we can add the example back to the docs.

From dotnet nuget push -h
Config isn't a valid switch. nuget push does have config as a valid switch. I'm assuming we should add it to dotnet nuget push, then doc it.
