Brecht Van Lommel 84daddc2fa Editor preview support for external renderers (#23333) ... Remove `[repository.editor] PREVIEWABLE_FILE_MODES` setting that seemed like it was intended to support this but did not work. Instead, whenever viewing a file shows a preview, also have a Preview tab in the file editor. Add new `/markup` web and API endpoints with `comment`, `gfm`, `markdown` and new `file` mode that uses a file path to determine the renderer. Remove `/markdown` web endpoint but keep the API for backwards and GitHub compatibility. ## ⚠️ BREAKING ⚠️ The `[repository.editor] PREVIEWABLE_FILE_MODES` setting was removed. This setting served no practical purpose and was not working correctly. Instead a preview tab is always shown in the file editor when supported. --------- Co-authored-by: zeripath <art27@cantab.net> Co-authored-by: Lunny Xiao <xiaolunwen@gmail.com>		2023-03-24 14:12:23 +08:00
