[issue33917] Fix and document idlelib/idle_test/template.py

[Terry J. Reedy]

Terry J. Reedy <tjreedy at udel.edu> added the comment:

I wrote it intentionally the way it is, for #33855, as it made it maximally easily to use to complete the test suite.  Since it caused a problem, I added a valid dummy name to be replaced, and fixed the other syntax error.  The file now compiles, runs, and tests OK.  New IDLE modules needing a new test file should be rare.

I will submit the PR after I edit the readme to document the usage of the template.
