Use dash for unordered lists

[andreoliwa]

Summary

Change the unordered list bullet from asterisk (*) to dash (-).

Why?

1. Prettier formats Markdown with dashes, see https://github.com/prettier/prettier/issues/4251
2. Logseq also uses dashes for unordered lists. Pasting multiple links with asterisks is not recognized as a list by Logseq.

I'm aware that the specs allow both of them though:

• Lists | Daring Fireball: Markdown Syntax Documentation
• List items | CommonMark Spec

Tests

I use Brave Browser, which is Chromium-compatible and can use Chrome extensions.

So I only tested on this one.

• [x] Brave Browser stable (macOS)
• [ ] Chrome stable (macOS)
• [ ] Firefox stable (macOS)
• [ ] Chrome stable (Windows)
• [ ] Firefox stable (Windows)

Optional:

• [x] Brave Browser beta (macOS)
• [ ] Chrome beta (macOS)
• [ ] Firefox beta (macOS)
• [ ] Chrome beta (Windows)
• [ ] Firefox beta (Windows)

Thanks. I also noticed that I am using - in the release notes.

However since this is a change of default behavior, I'd like to add an option so that users can choose which syntax to use. I will merge your changes and introduce another patch that implements the options UI.

This change has been shipped to Chrome Web Store, Edge Add-Ons and Firefox Add-Ons!
