DOCS: Clean dotnet database geometry

[SMoraisAnsys]

Change have been performed to update type hints / doc strings in src/pyedb/dotnet/database/geometry files.

On top of that, I updated the PolygonData init method because it contained arguments that were not used at all.

I would also advise to update the is_inside method which is currently working with x, y arguments but, in some cases, accepts that x can be a list and, on the fly, assigns x and y internally to match that situation. I find that very non intuitive and would prefer this method to only work with two float/str as argument.
