Use Monaco Editor

[NghiaTranUIT]

Description

We should use Monaco Editor instead of CodeMirror.

Acceptance Criteria

• Replace the Body CodeMirror with Monaco Editor
• Search the entire app, and replace CodeMirror with Monaco Editor
• Remove CodeMirror logic from package.json
• Make sure the Code Syntax Highlighting is working. For example, if the body is JSON -> set modelLanague is JSON, ... Apply for CSS, HTML, JS
• Make sure the JSON/JS worker is working. We can verify if we can collapse/extend the JSON Node, JS function body { }, and have the red line if the JSON is malformed. (See the following video)
