Multiplayer fix for Age of Empires II: Definitive Edition

This script fixes multiplayer "Out of sync" error in Age of Empires II: Definitive Edition using Proton. It will check if ucrtbase.dll is installed and installs it if necessary. Set the Steam launch options below to run it automatically before launching the game.

/path/to/script/run.sh ; %command% %steam_location%

For example, if repo is cloned to the $HOME/.local/share directory, then set launch option to the following:

~/.local/share/aoe2de-proton-mpfix/run.sh ; %command% %steam_location%

If %steam_location% is not set, the script will default to $HOME/.local/share.
