Arm Learning Path fails due to no download.sh script

[hybotix]

I am trying to complete the Arm Learning Path at:
https://learn.arm.com/learning-paths/embedded-systems/rpi-llama3

It fails at the point where it is time to download llama 3.1 because there is no download.sh script present to use.

How can I properly download the required model so I can continue working through this Learning Path? Instructions for doing so are confusing and very unclear.
