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...
