[Misc] Add data for theoretical Valentine's event (#5244)

* Add Valentines event data

* Event ends Feb 21 not March 21

* Event starts Feb 11 12:00 UTC for testing on beta

* Oops I meant February 10

* Add Luvdisc +3 Luck Boost

* Added Applin to round out the total pokemon and because I know people are going to be confused why it isn't here if they've actually read in gen 8 (any readers in chat?)
