Subject: [PATCH] Editor: Add unit test for Comment Template block.

Backport of 2 tests from Gutenberg for the Comment Template block:

* test line and paragraph breaks are converted into HTML tags.
* test rendering of unapproved comment preview.

Follow-up to [53298], [53172], [53138].

Props bernhard-reiter, darerodz, gziolo, peterwilsoncc, hellofromTonya.
Fixes #55643.
See #55634.
