fix(learn): address escaped backticks (#40717)

* fix(learn): address escaped backticks

Addresses the instances of escaped backticks - where a backtick is
preceded by a backslash.  In most cases, this was left over from the
old parser. In some cases, a backtick was intended to be wrapped in
code tags and has been adjusted accordingly.

This issue came to light due to a bug in the translation flow on
Crowdin.
