Fix VERSION_LONG format

VERSION_LONG is used for the CFBundleVersion, which App Store Connects
expects to be an ever increasing integer.

Using a SemVer-style value, results in the following error:

> This bundle is invalid. The value for key CFBundleVersion
> [1.11.1.0] in the Info.plist file must contain a higher version than
> that of the previously uploaded version [11103].
