Update Editor to use Markdown
We currently use Quill as our WYSIWG editor. This approach leads to vulnerabilities and sometimes a bad UX when we make an interop between different services. To solve this problem, we will use a Markdown editor. The editor should be primarily for people who are not familiar with Markdown, so it will remain as a WYSIWG editor.
It would be great if there was an advanced option for people who are familiar with Markdown.
