Subject: feat: add modrinth pack downloading

Things that don't work / work poorly (there's more for sure but those
are the evident ones):
    - Icons are broken in the import dialog
    - No way to search for private packs
    - Icons are not downloaded when downloading a mod
    - No support for multiple download URLs
    - Probably a lot more...
