Configure basic HTML input format to NOT use markdown at all

Was considering doing this anyway because switching between the Markdown WYSIWYG
and regular CKEditor could really screw up formatting, but after the upgrade of
the Markdown module (which provides the underlying Markdown capability that
CKEditor Markdown uses, apparently) it absolutely destroyed every port of content
that was using the Basic HTML input format, in the way described way back in this
old comment on the upgrade issue, https://www.drupal.org/project/markdown/issues/3103679#comment-14289153

Anyway this configuration change fixed the major problem of the text being output with
no HTML formatting whatsoever.
