editor: Improve JSDoc extend comment on newline to follow convention (#30800)

Follow up for https://github.com/zed-industries/zed/pull/30768

This PR makes JSDoc auto comment on new line lot better by:

- Inserting delimiters regardless of whether previous delimiters have
trailing spaces or not
- When on start tag, auto-indenting both prefix and end tag upon new
line

This makes it correct as per convention out of the box. No need to
manually adjust spaces on every new line.

Release Notes:

- Improved JSDoc auto-commenting on newline which now correctly indents
as per convention.
