The previous documentation appeared to be out of date with regards to the setup which had recommended getting godot-cpp -b 4.x which are no longer available since 4.6 and beyond. Further, I feel we need to add build instructions for the godot-cpp module since without building it, none of the includes used afterwards are present and can be confusing to someone starting out why sprite2d.hpp is not available. Finally, I think most people using an IDE requires compile_commands.json to be present for their LSPs to work (for example I'm using clangd, and autocomplete wouldn't work until it generated) so I added a section to generate it. This hopefully will provide a more fluid intro without having to use reddit or forum posts to patch it together.
