Increase repeated weed expansion delay for the same tile (#5772)

# About the pull request

This PR tweaks the delay required to expand weeds to the same tile. As
in when a marine destroys weeds a queen just expanded, she must wait
this much delay to spread it to that location again.

# Explain why it's good for the game

Disincentives using weeds next to marines slightly
