Removes the scrollbar from the 'Player setup' menu (#5049)

# About the pull request

Removes the scrollbar from the pre-roundstart 'Player setup' menu by
increasing its height slightly.

# Explain why it's good for the game

There's nowhere to actually scroll to, so it's just taking up a big
chunk of the space on the right side of the window.
