Missing scons command in GDExtension C++ example docs, also potentially outdated command when git cloning

[PabloIsCoding]

Your Godot version: 4.2

Issue description: Missing command (and possibly an outdated one also) in docs

URL to the documentation page: https://docs.godotengine.org/en/stable/tutorials/scripting/gdextension/gdextension_cpp_example.html

The docs say:

"To generate and compile the bindings, use this command (replacing with windows, linux or macos depending on your OS):

The build process automatically detects the number of CPU threads [...]"

So there is a missing command in between those lines. I believe the missing command is scons platform=<platform> but this is my first time doing this so idk. There is also a call to scons later on, so maybe this one is redundant.

Also, I noticed that when cloning the repo it forces the 4.1 branch, but I think it should clone the 4.2 (?)

Hope this helps

Following the guide in godot 4.2 I couldn't make the example work, but it worked when switching to 4.1, so maybe it's good that the clone commands gets the 4.1. Still, there should be a warning specifying that this will only work in 4.1.

@PabloIsCoding Can you provide some details about what went wrong? Was there an error? Making an issue on the godot-cpp repo would be much appreciated

[PabloIsCoding]

Well I tried to reproduce it today from scratch and it works. My guess is that I was either compiling the godot-cpp master branch or the 4.1 branch instead of 4.2.

Question: isn't 4.2 the latest stable version? The docs for the cpp example still seem to point to 4.1

The 4.2 docs (https://docs.godotengine.org/en/4.2/tutorials/scripting/gdextension/gdextension_cpp_example.html) say:

mkdir gdextension_cpp_example
cd gdextension_cpp_example
git clone -b 4.2 https://github.com/godotengine/godot-cpp

While stable (https://docs.godotengine.org/en/stable/tutorials/scripting/gdextension/gdextension_cpp_example.html) says

mkdir gdextension_cpp_example
cd gdextension_cpp_example
git clone -b 4.1 https://github.com/godotengine/godot-cpp
