2.0rc2: Sparkle URLs collect sparkle:version key value in output instead of sparkle:shortVersionString

[apizz]

Describe the bug
Recently created this recipe manually, so I wanted to test it with latest RC of v2. When I drag the app (MTMR - https://github.com/Toxblh/MTMR) into Recipe Robot it outputs the CFBundleVersion of the app (listed as sparkle:version in the appcast.xml) from the app's Sparkle feed instead of CFBundleShortVersionString (listed as sparkle:shortVersionString). Later on when the app's version is collected, Recipe Robot uses the CFBundleShortVersionString, which doesn't match. Ultimately this is more of an output mismatch rather than a true bug.

To Reproduce
Steps to reproduce the behavior:

1. Download MTMR app from GitHub
2. Mount the DMG
3. Drag the app into Recipe Robot v2.0rc2
4. What for completion.
5. Note in output version is listed as 406, which is the app CFBundleVersion, not CFBundleShortVersionString, and that later when a version is collected directly from the downloaded app that 0.26.1 is collected.

Expected behavior
Version key collected from Sparkle feed matches the version key later collected from app.

Thanks, this is a good suggestion.

First, it should be noted that the versions discovered during Sparkle feed inspection are used only to determine which Sparkle enclosure item should be used as "latest," and needn't match the actual application downloaded.

That said, I could see how showing more version info from the Sparkle feed could be useful. I'll add shortVersionString output in addition to the current version output.
