Most tutorial shader code is still in GLSL and not Slang

[katas94]

After the recent tutorial update to use the VulkanHpp headers and RAII, I also noticed that it migrated from GLSL to Slang shaders. The source code links at the bottom of each chapter is now pointing to the updated RAII C++20 code, but are still pointing to the old GLSL shaders, which won't work since we are not expecting to load the Slang one. It looks like we only get the first Slang shader link starting at the Texture Mapping chapter.

Also there is a typo in the Drawing a triangle > Graphics pipeline basics > Shader modules section when describing the Windows bat script. slang.exe should be slangc.exe

Thanks for this report, I'll make a PR to address this. The code is all there for both GLSL and slang, but the links are not.
