Subject: [PATCH] Revert "apply missed version update"

This reverts commit d6f1835532f84d26b388bcba523be459a2a93a81.

This was an intentional change to match the correct compatibility version on macOS

For example, 2.32.1 would have the following:
/usr/local/lib/libSDL2-2.0.0.dylib (compatibility version 3201.0.0, current version 3201.1.0)
