Add explanation about how to use only emojis as read statuses

[Dominic-DallOsto]

Hmm, it works for me on Windows, but I had to manually update all the item's read statuses from their text to their emoji versions

But yeah, this will still show the emoji in front of the title because I think Zotero does this whenever there's an emoji in the tag

This is really a workaround, but before we can recommend it - need to fix #26 so that you don't need to manually relabel the read status of all of your items
