Introduce GitHub markdown editor, keep EasyMDE as fallback (#23876)
The first step of the plan * #23290 Thanks to @silverwind for the first try in #15394 . Close #10729 and a lot of related issues. The EasyMDE is not removed, now it works as a fallback, users can switch between these two editors. Editor list: * Issue / PR comment * Issue / PR comment edit * Issue / PR comment quote reply * PR diff view, inline comment * PR diff view, inline comment edit * PR diff view, inline comment quote reply * Release editor * Wiki editor Some editors have attached dropzone Screenshots: <details>     </details> --------- Co-authored-by: silverwind <me@silverwind.io>pull/22994/head^2
