CI,cmake: Fix macOS version information

Fixes an issue where on macOS the app’s Info window in Finder would say
"Version: OBS - Free and Open Source Streaming/Recording Software"
instead of the version set in CFBundleShortVersionString.

Since CFBundleGetInfoString is deprecated anyways, it can safely be
removed.
