Boost For Lemmy

Insert Link dialog is inserting a ! symbol before the URL? which makes Boost not render it as a link, I don't know if that's the behavior on web Lemmy.

Repro:

• Start a new post or comment
• Press the link button on the toolbar
• Fill the form and insert the link
• The resulting markdown looks like this:

![Some URL](https://example.com)

If you press the preview (magnifier) button, it doesn't show as a link, and this continues after you post the new message

The other thing is that both fields of the Insert Link dialog have the placeholder "URL". I know the icons are different but at first glance I found it confusing
