Suggestions for minor improvements to the documentation

[NiklasRentzCAU]

While going through the documentation, I found some small issues that I do not know the exact answers to, so I wanted to leave them here for clarification before trying to fix these myself:

All in in 3. Tools and Environments:

• the links to "Installation Instructions" and "Resources" lead to non-existent pages, where should they lead instead?
• when using the nix setup, it seems to be necessary to follow the pico-examples readme first and install this:

sudo apt install cmake gcc-arm-none-eabi libnewlib-arm-none-eabi libstdc++-arm-none-eabi-newlib

• in the "Using VS Code" section it might be good to and another hint that nix develop needs to be executed first in the lf-3pi repository first as well.
• using screen may skip some outputs that are not shown on the computer's terminal. I don't know the exact reason why this is, but an explanation for that could help the reader.

Thanks for the feedback! I've pushed a fix for the first and third bullet items.
For the second bullet item, I thought the template repo was supposed to include these tools automatically. Did you run
git submodule update --init? If that is not sufficient, where exactly would you suggest putting these instructions?
As for the fourth, I have not seen this phenomenon and have no insights on why it might be occurring, unfortunately...

Feel free to issue a pull request for any and all improvements that come to mind, and thanks for these!

Only if your in a nix-configured shell (i.e., after running nix develop). Maybe @NiklasRentzCAU was operating in a "normal" shell?

When opening VS Code in the required folder I first did not find the "gcc-arm-none-eabi" until after doing this manual installation. I did do git submodule update --init first, but its possible that I did not have a nix-configured shell up at that moment. I cannot re-test it now as after this installation it now works.
