Integrate a Code editor in the Code Snippets form

[mnamegaurav]

Currently there is no option to highlight the syntax in Code Snippets form, like we see in VSCode or any other IDEs.

My recommended choice is to go for Monaco Editor which is being used by Microsoft for VSCode syntax highlighting. https://github.com/Microsoft/monaco-editor

This is a versatile editor for browsers, we can use it for input forms as well as for highlighting purposes on Code snippets page.
