* 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 Co-authored-by: Lauris BH <lauris@nix.lv> Co-authored-by: techknowlogick <techknowlogick@gitea.io>
