Incorrect Namespacing in Camera2DDemo Example and probably others

Issue description

After creating a blank project using dotnet new console and adding Raylib-cs with dotnet add package Raylib-cs, the code sample provided here doesn't work out of the box which I imagine that it should (I could be wrong and please point out if I am. I'm new to C# and I don't really know how things work just yet)

Environment and other useful information

OS: Linux (Arch Linux)
Mesa drives version: 1:24.0.7-3
Raylib version: 5.0-1
Raylib-cs version: 6.0.0

Reproducing errors

mkdir test/
cd test/
dotnet new console
dotnet add package Raylib-cs

copy code from Examples/Core/Camera2dDemo.cs into the generated Program.cs. Run:

dotnet run

The build failed. Fix the build errors and run again.

Temporary fix

I managed to make it work by changing using static Raylib_cs.Raylib to using Raylib_cs and adding Raylib. at the beginning of some types. Not all of them needed tho, Rectangle, Camera2D and Color are examples that only worked without the namespace.
