Dropped the pre-release version from bundle short version string (#2808)

It appears that iTMSTransporter only allows a CFBundleShortVersionString to have at most three non-negative integers. See PR #2799 for more info.

ERROR ITMS-90060: "This bundle is invalid. The value for key CFBundleShortVersionString '5.0.0.beta.5' in the Info.plist file must be a period-separated list of at most three non-negative integers. Please find more information about CFBundleShortVersionString at https://developer.apple.com/documentation/bundleresources/information_property_list/cfbundleshortversionstring"
The call to the iTMSTransporter completed with a non-zero exit status: 1. This indicates a failure.
