[Feature] Add a 'select-apps' interactive prompt, to choose which games to prefill

This should implement an select-apps command that displays an interactive prompt that allows users to choose which games to prefill. It should be implemented similarly to how it is done in SteamPrefill This would improve the overall usability for users, as they will no longer need to know the relationship between game titles <-> product codes.
It would additionally bring BattleNetPrefill to have more consistency across all of the prefill apps.
