Could we refactor the function TrN and make them share the same code?

gitea/modules/templates/helper.go

Line 898 in a3d6850

func TrN(lang string, cnt interface{}, key1, keyN string) string {

IMO we should have a unified behavior in both template and backend code.

ps: the old TrN need to be refactored, too. The templates call it by {{.i18n.Tr (TrN .i18n.Lang ... ) }}, it is complex and might be simplified to {{.i18n.TrN ....}} directly.

That could be another PR.

Please send backport.

I proposed a refactoring for TrN:
