Split version for CI environment doesn't actually work fully in practice

[JessicaTegner]

Hi there.

The split version argument doesn't work fully as intended, because in some places, the mac/win/linux version information are still stored in the same file regardless. Following are all of the places that would needed to be split up, for this to work 100% of the time

• versions.gz
• keys.gz..pyupdater/config.pyu

Hope someone can take a look at this
