Add paper's EntityFertilizeEgg event

[CJH3139]

Problem

https://github.com/SkriptLang/Skript/issues/7819

Solution

• Added a bonemeal alias to Block Fertilize event as it was a little bit confusing to some ([block] fertilize -> "[block] (fertilize|bone[ ]meal)")
• Added paper's EntityFertilizeEgg event that accepts mother and father entity from the breeding family expr
  • Errors when using event-entity as it's ambiguous
  • Errors when using child from ExprBreedingFamily (Still in blockstate or not an entity at all in some case)

Testing Completed

Tested both with a script and manually

    broadcast "Mother is: %breeding mother%"
    broadcast "Father is: %breeding father%"

oh and on the error message screenshot, changed the first error message line to The 'bred child' expression cannot be used in a 'fertilize egg' event.
