Feature Request: Support Command Aliases

[roumcha]

(Previous issue title: Aliases are displayed twice in command list)

On the command help, command aliases are displayed twice.

Sample

Code

var app =
    ConsoleApp.Create(args)
    .AddCommands<Program>();

app.Run();

partial class Program : ConsoleAppBase
{
    [Command(new[] { "s", "sa", "sample" }, "Sample command.")]
    public void Sample() {
        Console.WriteLine("Hello from console app!");
    }
}

Output of dotnet run help

Commands:
  help                        Display help.
  s, sa, sample sa, sample    Sample command.
  version                     Display version.

Aliases sa and sample are displayed twice.

Cause

commandHelpDefinitions.Select(... in method BuildMethodListMessage (here) seems to generate the wrong help text.

x.Command already contains the aliases, but it gets concatinated with x.CommandAliases.

Environment

• ConsoleAppFramework 4.2.4
• .NET SDK 7.0.101
• Windows 10 Pro 22H2 x64

I read the readme.md again and realized that it doesn't mention command aliases. Sorry.

So, please let this issue be a feature request for command aliases, if it has not yet been officially available.
