This addresses issue 5084 by partially reverting commit `fefed147`. In said
commit, we updated `THIS_VERSION` to utilize `MAJOR_VERSION` which is fine.
However, we also updated the deploy module to copy the same format. This
interferes with the osTicket Version check by not including the entire
subversion and not starting with a `v` (ie. `v1.12.3`). This reverts the
copied format section of the commit so that `THIS_VERSION` will be the full,
non-git version when deployed/packaged.
