Option to sort addons by date added

[DNin01]

Why this would be helpful/solve a problem

It might be kind of nice to see the addons in the order they were added. For me, it might help to see the newest addons so I can fill in their images.

What this change does

Adds a way to sort the addon list on https://scratchaddons.com/addons/ by date added, not just alphabetically.

Possible alternatives

Refer to the changelog.

Demonstration(s) and additional context

I don't have anything else to show.

This would be nice to add. We could use the versionAdded property of addon manifests.

This would be nice to add. We could use the versionAdded property of addon manifests.

And also sort multiple addons in the same version using addons.json order (as addons are usually placed after eachother, the exception being themes).

And also sort multiple addons in the same version using addons.json order

This could be done but isn't very necessary. We don't add more than 5 new addons per release anyway.
