Python version mismatch

[RivenSkaye]

There's a mismatch between the prerequisite and preface version listings. pre-requisite-installations says it was tested on Python 3.12 and might require editing or produce different messages and error logs for other Python versions, whereas the preface notes the book was updated for use with Python 3.11.

The image embedded on the pre-requisite-installations page shows the 3.11 installer as well.

thanks for this! I'll update the preface and make a note to take a new screenshot. Carry on with 3.12 if you aren't already!
