HorizontalLine - Add margin parameter in the `QuickDisplay` method

[lastunicorn]

As a developer using the HorizontalLine control I want to be able to provide a margin parameter when using the QuickDisplay approach so that I am able to write more compact code.

Instead of adding new parameters to the static method, I created one that lets the caller set any property on the HorizontalLine before displaying it.

Usage:

HorizontalLine.QuickDisplay(horizontalLine =>
{
    horizontalLine.Margin = 10;
    horizontalLine.ForegroundColor = ConsoleColor.Blue;
});
