Using the new and more precice `TimeProvider` for `ProgressTask` instead of `DateTime`

[FaustVX]

Is your feature request related to a problem? Please describe.
In my current project, I need to have a precise elapsed time column for my progress tasks, but they are all shown as 00:00:00 because there are too quick, and I need to see the ms also.

Describe the solution you'd like
I've changed the ProgressTask.StartTime & ProgressTask.StopTime properties to long? then use the new API from .NET8: TimeProvider.System.GetTimestamp() & TimeProvider.System.GetElapsedTime()

Describe alternatives you've considered
I didn't see any alternatives.

await AnsiConsole.Progress()
    .Columns([
        new TaskDescriptionColumn(),
        new ProgressBarColumn(),
        new ElapsedTimeColumn() { Format = null }, // change the new Format property
    ]).StartAsync(...);

ElepsedTimeColumn.cs

public string? Format { get; set; } = @"hh\:mm\:ss";

public override IRenderable Render(RenderOptions options, ProgressTask task, TimeSpan deltaTime)
{
    // ...
    return new Text($"{elapsed.Value.ToString(Format)}", Style ?? Style.Plain);
}

I'm already using the modified version in my project flawlessly and am able to create the PR now.
All the tests run fine.
