[PATCH 1/1] doc: replace docutils.utils.error_reporting

[Heinrich Schuchardt]

Docutils has dropped reprunicode(), ErrorString() and SafeString() in newer
revisions. This stops us from using a current docutils, e.g. 0.22.4.

Use the same definition of ErrorString() as Linux v6.18.
Drop reprunicode() conversion.
