Update markdown styles for quoted lists
What does this MR do and why?
Updates markdown styles for quoted lists
Makes lists rendered in markdown use the same "list style" as normal when they're quoted. See screenshots for examples.
Fixes list style being inconsistent between quoted and unquoted lists.
Also fixes list style of quoted lists changing when clicking to reply to a comment (see #28700 (closed) description for video example of this issue)

How to set up and validate locally
Numbered steps to set up and validate the change are strongly suggested.
- Visit anywhere markdown is written and subsequently rendered (e.g. an Issue discussion).
- Write a comment containing a list.
- Quote the list in another comment.
- Check that the list style (the bullet point 'marks') match between the normal and quoted lists.
- This should also work for nested lists as shown in the screenshots above.
