Update winetricks formula

Winetricks formula was pretty out of date. This makes me sad, because it caused winetricks to not install some libraries correctly, and thus I had to manually install it, instead of a simple brew install winetricks.

This updates the formula to the (current latest) version.

Closes #28913.
