fix: prerelease generated version strings that could not be compared (#72)

fix an issue where functions like PHP's `version_compare` would
incorrectly compare a PR build to a pre-existing published version.

we now always append the number of "commits since tag" number so that
any build is more likely to be able to be correctly compared and return
a greater version number than actual older versions

fixes INT-876
