CommandSettings Branch Inheritance Not Displayed In Help

[brandonryan]

When you have a config like:

appConf
    .AddBranch<MyBranchCliOptions>("mybranch", conf =>
    {
        conf.AddCommand<MyCommandCliOptions>("mycommand")
            .WithDescription("a command description")
    });

then you run dotnet run -- mybranch mycommand --help it only displays the help from MyCommandCliOptions excluding the inherited properties from MyBranchCliOptions.

public class MyBranchCliOptions: CommandSettings
{
    //properties here will not be shown in help
}

public class MyCommandCliOptions: MyBranchCliOptions
{
    //properties here will be shown in help
}

If you change

conf.AddCommand<MyCommandCliOptions>("mycommand")

to

conf.AddCommand("mycommand")

it works as expected but now my command settings for .AddCommand<> aren't enforced to inherit from the branch settings.

Additionally, when you ask --help at the branch level it shows properly. Probably an issue with reflection params when trying to get the attributes from the properties?
