[1.22] p.52: example with --become-user

[mkrawczuk]

The -U shorthand for the --become-user argument is not recognized:

$ ansible-playbook -U johndoe playbook.yml

Seems like it has been removed. I will look through the release notes in spare time.

By the way - have you considered putting the book's source into github, so that ready fixes would be proposed right away in form of PRs?

@mkrawczuk - Yeah it looks like that was stripped out in this commit (ansible/ansible@445ff39) from Feb 2019. Good catch! I'll have this updated in version 1.23, coming soon!

At this point, I'm still keeping the source manuscript repo private because there's a lot of other stuff in it for the full book build, including many proprietary assets that I'm not sure I could put under an open source or CC license.

But at some point it's an option I'm considering exploring. Thanks again for posting these issues!
