Option are displayed in lowercase in help

[sybaris]

Describe the bug
When no long or short name is provided for an option, the help display this option in lowercase

To Reproduce
Run this console program adding in the command line "--help "

    class Options
    {
        [Option(HelpText = "Specify the input file.")]
        public string InputFile { get; set; }
    }

    class Program
    {
        static void Main(string[] args)
        {
            var result = Parser.Default.ParseArguments<Options>(args);
            result.WithParsed(options =>
                {
                    Console.WriteLine($"InputFile: {options.InputFile}");
                })
                .WithNotParsed(errors =>
                {
                });
        }
    }

Expected behavior
"InputFile" instead of "inputfile"

Screenshots

Additional context
I saw that it's in Specification.cs class method FromProperty that there is a call to ToLowerInvariant() that make the display lower

This is the default behaviour defined like this by the standard.

You can specify a custom longName for the option like this:

class Options
    {
        [Option(longName: "InputFile", HelpText = "Specify the input file.")]
        public string InputFile { get; set; }
    }

Thanks for your answer.
I agree that specifying a longname solves the problem.
This requires specifying a longname for all options :-(
But I find it really unfortunate to have this default behavior...
