The fetch_mldata() function was removed 3 or 4 years ago, because the website it relied on was no longer maintained.
It was replaced with fetch_openml(), which relies on the well-maintained openml.org website.
See this issue #301 for more details.
Also note that fetch_openml() changed recently, so in the latest versions of Scikit-Learn, you will need to add the argument as_frame=False to ensure that the code examples still work.
Lastly, the 1st edition of my book is becoming a bit old now. The 2nd edition was released in 2019, and the 3rd edition is coming out soon. The early release is already available here. And the up-to-date code is in the https://github.com/ageron/handson-ml3 repository.
