Here's the code as I ran it:

import tensorflow as tf
from pathlib import Path

# extra code – downloads a pretrained model
url = "https://github.com/ageron/data/raw/main/shakespeare_model.tgz"
path = tf.keras.utils.get_file("shakespeare_model.tgz", url, extract=True)
model_path = Path(path).with_name("shakespeare_model")
#shakespeare_model = tf.keras.models.load_model(model_path)

The stack trace I got:

Please what am I doing wrong?

Your code looks good to me, in fact I've just tested it and it works fine. This might just be a temporary issue on github, you could just try again and hopefully it will work. If not, then it's probably a network issue: check your router, wifi, firewall, and so on. If nothing works, you can try downloading the file manually, and place it in <your home folder>/.keras/datasets, then run the code again.
