Update MauiOxyTouchEventArgs.cs

Change access modifier to match constructor

Allows access to public property when instance of this class is returned

PointerCount appears to exist to facilitate some internal Maui specific logic; however, I'm unfamiliar with Maui, and it looks like the Oxyplot-Maui provision may have some outstanding issues with touch support, so I wouldn't be surprised if this was liable to change.

What's your need for accessing the PointerCount?

[SimGoodwinHWM]

I agree it will probably change, though the OxyPlot PlotController methods for handling touch events also use OxyTouchEventArgs so this may still apply with further changes, if touch controlls continue to be supported.

I was hoping to use it with the (admittedly depreciated) PlotModel.TouchCompleted event to assist in determining user intent, specifically whether they are trying to zoom in or move an element on a fully zoomed out graph.

I don't see a good reason why we shouldn't allow access to PointerCount, so: Ok with me! 👍

Merged. Thanks for the contribution!
