[issue30290] IDLE: add tests for help_about.py

[Terry J. Reedy]

I am about to go to bed, way late.

I would like to review and apply all the non-test changes, 4,5,6 in one PR, and add 3 since I know what I meant.  There can be multiple commits in one PR though.

Louie, from #30422 and a tracker search, you can see that there is lots to do, for more that 1 or even 2 people.  I think 4,5,6 are a good way for Cheryl to start with IDLE.  Other files need similar changes that do  not need your tkinter skills.

If you are looking for a useful challenge, there are 12 open IDLE debugger issues + some enhancements debugger ideas I have not bothered to post yet.  If that does not interest you, I can try to suggest something else after I get up again.

I expect to be away from my computer on my Monday.
