Disable all typographic replacements in markdown renderer (#11871)

* Disable all typographic replacements in markdown renderer

Previously we only disabled some of them. This disables all the default
replacements that goldmark's typographer extension offers, matching
GitHub's renderer.

Ref: https://github.com/yuin/goldmark#typographer-extension
Fixes: https://github.com/go-gitea/gitea/issues/11001

* remove typographer extension completely

* fix test

* really fix test
