Queen give_evo changes (#5505)

# About the pull request

changes the required_larva to 1 instead of 3

# Explain why it's good for the game

with our pop we never have 3 burrowed larva, i still think it wont be
able to get used even with the limit being one because of how our que
system and etc works but atleast this should make it get used more
compared to the 3 burrowed limit
