Switch to using CFBundleVersion instead of CFBundleShortVersionString for the default

[brysontyrrell]

There is a discrepancy between definitions and patch data generated by patchstarter.py and Jamf's official patch feed. The official definitions do seem to be using CFBundleVersion and not CFBundleShortVersionString.

To better align with the official feed, I plan to change the behavior in patchstarter.py to use CFBundleVersion. I will include a new argument --short-version to force the script to reference CFBundleShortVersionString to preserve the original behavior for those who wish to continue using it.

Looking for comments before implementing this change.
