[0.18.8] 'PvP' and 'Team production' mode description improperly says multiplayer-only

[Arphox]

Bug description:
PvP and Team production game modes' description text states that "This is a multiplayer-only scenario.", however this is not true since they can be played in single player as well.

The text is the same in both ways of creating such game so this bug applies to both "paths":
A) Single player → New game / Game scenarios:
B) Multiplayer → Host new game / Game scenarios:

Assumed severity
LOW. Written deception of the player, does not affect gameplay, may confuse minor confusion.

Its not a bug, but I will look at clarifying the description
