MT-4449 Editor - Detect ordered and unordered lists, headings and quotes

From Productboard from @jesse :

if you start typing certain characters like: * or - or 1.

--

General rules

I found two patterns on what happens if you create a list by typing */-/1./>/#/## + space and then press the Backspace key, and this indeed will solve the issue you pointed about achieving having the shortcut characters as regular text.

Notion and Craft will remove everything, both the format and the introduced characters will disappear from the line. This is very frustrating.

Google Docs and Coda will remove the formatting, you get a regular, unformatted */-/1./>/#/## content and you can continue typing an unformatted line. This is what I found most useful and will allow users to choose the desired output: https://cln.sh/ArqoHP. This is how it should behave.

List of shortcuts

• 1. → Ordered list
• - → Unordered list
• * → Unordered list
• > → Quote
• # → Heading 1
• ## → Heading 2
