refactor: ♻️ demote log messages (#330)

Demote the log message in `ModLoaderUserProfile` regarding "no `mod_ids` inside `mod_list`" from a warning to an info level. Similarly, demote the log message in `_ModLoaderFile` about "can't open mod folder" from an error to an info level. This adjustment is aimed at preventing confusion after the mod loader is running for the first time without any mods.

closes #327
