Small issue in README: pip links is not align with notebook

[xavierforge]

Hi, thanks for the puzzles 😀
I found that the pip install links in README are as follows

But the notebook is updated to

!pip install -qqq git+https://github.com/chalk-diagrams/planar git+https://github.com/danoneata/chalk@srush-patch-1
!wget -q https://github.com/srush/GPU-Puzzles/raw/main/robot.png https://github.com/srush/GPU-Puzzles/raw/main/lib.py

I tried the one in README, but it is not working now.
