Check on Matching Exercises

[braughtg]

Matching exercises do not seem to be rendering in the Code Chat or the Web target. Has something changed in the way they are specified in the new version of PreText?

Matching exercises need a feedback block after the statement block and before the matches block. See https://pretextbook.org/examples/sample-book/annotated/matching-exercises.html for an example.

I am going to reopen this as a reminder to check the Matching exercises in every chapter before we publish.
