Fix Spanish and Latin Spanish translation for Partner Anniversary
The translation for "Happy Partner Anniversary" should be "Feliz aniversario de Partner PartyHat" for both Spanish and Latin American Spanish
The Latin Spanish current message is "¡Feliz aniversario de Partner con PartyHat!"
This message translates to "¡Happy Partner anniversary with PartyHat" which is close to the actual message but the word "con" shouldn't be there.
And the Spanish current message is "¡Feliz aniversario de asociación con PartyHat!"
Which translates into "Happy association anniversary with PartyHat!" which is pretty far from the original message and it doesn't make that much sense when reading it.
Everyone uses the word Partner in the Spanish community, no need to translate that. That's why the message should be the same for both languages.
