Modpack marked as "unlisted" can be viewed through a collection

Firefox

Describe the bug

A modpack that is set to "unlisted" is 'advertised' as "Visible via URL only. Not shown on your profile or in search". However, when going through an existing, published modpack that is part of a collection of the same author, opening that collection will show the unlisted modpack.

If this is not an actual bug (aka 'feature') I would argue that the description in the visibility dropdown should be more clear about this

Steps to reproduce

1. Create two modpacks: One public, one unlisted
2. Add them both to a modpack collection
3. Search for the public modpack, then switch to the modpack collection through the Creators list
4. In that list, you will see the unlisted modpack shown and available to download

Expected behavior

I would expect unlisted modpacks to not be listed in a modpack collection.
