Do not emit ambiguous character warning on wiki pages

[adigitoleo]

Description

The warning in question was discussed in #20999, and it was decided that it should not be presented on rendered pages.

The PR #22018 was merged to address this, however I still see the warning on wiki pages at codeberg. The PR modifies the repo template but perhaps a wiki template file also needs to be patched.

Codeberg is using a forked Gitea 1.19.2:
