refactor: correct version variables

These two variables have been the wrong way around for a while. In
preparation for splitting Doom into separate repos (its core and module
libraries), I've corrected them. doom-modules-version is a placeholder
and will be removed later.

I've also settled on -dev suffix for inter-release versions of Doom,
rather than alpha.
