Add cache command for managing downloaded installers

[ryfu-msft]

This pull request resolves #62

Changes:

• Change installer download path from %temp% -> %temp%/wingetcreate
• Created a cache command that opens the cache folder, lists downloaded installers, and cleans out all downloaded installers
• Changed basecommand.githubtoken to be a virtual property that can be overrided so that commands like settings and cache don't inherit the --token option
• Removes GetVerbs() from program.cs as this was displaying commands in alphabetical order. Reverted to listing out the commands in an array to have an ordering based on usage.
• Added cache command documentation

Testing:

• Added unit tests for the cache command

Hit an unrelated error where if the AppStatePath wasn't already created at first run, the program would crash. Recommend creating it just to be sure:

    private static readonly Lazy<string> AppStatePathLazy = new(() =>
    {
        string path = IsRunningAsUwp()
            ? ApplicationData.Current.LocalFolder.Path
            : Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.LocalApplicationData), "Microsoft", ModuleName);
        Directory.CreateDirectory(path);
        return path;
    });
