Substitute Link Icon Only For Sharing

But then this changes the icon in the editor, so it does not make sense to use a share icon to represent inserting a hyperlink. It would be helpful if there were separate API calls to reference the two contexts for this button, so I could substitute as a share link icon but not an insert link one.

This would require a Discourse change. We would have to duplicate this icon internally while keeping both versions using the same icon by default so downstream users can target each individually to change it.
