Bug Report
Current Behavior
When I add a Bluesky url, no card (embed) is displayed, just a link to the post, as seen in this screen capture below.
Steps to Reproduce
Expected Behavior
See an embedded skeet (instead of its link)
Screenshots

Environment
Possible solution(s)
Additional Context
I tested the S9e Text Formatter library outside of flarum and it works with those bluesky urls.
