Current behavior

Currently its working only in case if we define onShow hook at global level but not in a specified variation.
Following source code:

helipopper/projects/ngneat/helipopper/src/lib/tippy.directive.ts

Line 280 in 3c57990

 this.globalConfig.onShow?.(instance); 

onShow hook is calling only from global settings but i think we can add check is variation contain lifecycleHooks and then call them instead of global one.

Expected behavior

Ability to define lifecyclehooks in directive options or at variation level

What is the motivation / use case for changing the behavior?

Main motivation is to add more freedom of customization for tippy. My case is to hide any other tooltips that already opened to leave only single tooltip visible.
