Wrong ManaRegenerateEvent import for AuraSkills API

Line 3 in 283b809

import com.archyx.aureliumskills.api.event.ManaRegenerateEvent

This should be changed to:
import dev.aurelium.auraskills.api.event.mana.ManaRegenerateEvent
because it will cause erroneous behavior for the new AuraSkills 2.0 integration
