Tkinter documentation external links outdated?

[hugovk (Hugo van Kemenade)]

This links to Python and Tkinter Programming by John Grayson, published in 2000.

But the docs link to:

• Python and Tkinter Programming
  By Alan Moore. (ISBN 978-1788835886)

There’s a mistake here. This Moore book is really called Python GUI programming with Tkinter, and was published in 2018. I’ve opened a PR to fix the docs.
