[FEATURE] Support for Bluesky

Is your feature request related to a problem? Please describe.
There doesn't seem to be much for a media downloader for Bluesky.

Describe the solution you'd like
Either added support from this extension or a new extension to be able to download from Bluesky that would function exactly the same as for TwitterMediaHarvest.

Perhaps Bluesky doesn't have as large of a userbase to be considered but it does seem to be growing in popularity more than other Twitter alternatives.

Would also like to request this now that a lot more people have migrated over to bsky in the last few days. I use the Twitter harvester daily, and with a lot of creators and artists moving sites, it becomes harder to save media consistently between sites. 😅

This is the only thing holding me back from switching to Bluesky completely. Especially now, with Bluesky gaining more and more users, this would be an absolute godsend.
