git .modules about donut

[r2d2Proton]

Based on Ivan's comment to use --recurse-submodules.

Either the command I am entering is wrong, or it doesn't work the way we think it does. Again, it could be my misunderstanding. As you may know, donut has a dependency on nvrhi. I added a small modification "Test" under Introduction to nvrhi::README.md:

### Test

And cloned the donut repo with:

git clone --recursive https://github.com/r2d2Proton/donut
cd donut
git pull --recurse-submodules

Notice in the first image below Test is missing. Also notice that the head is detached in nvrhi. In the second image, after the git checkout main, the current files is pulled from the repo. Am I doing something wrong?

Git modules can be confusing, that's true. Explaining submodules is beyond the scope of this project or issue, but here's some article I found that may be helpful: https://gist.github.com/gitaarik/8735255

Closing.
