Odd prereleasePrefix behavior with non-prerelease change types #1098
Description
Currently if the prereleasePrefix option is specified, ALL packages with type major/minor/patch will instead be bumped as prerelease due to the logic in bumpPackageInfoVersion.
This dates back to #658, which appears to be a misunderstanding or different opinion about the intended behavior. As originally implemented in #459, prereleasePrefix would only apply for changeType: 'prerelease', which also makes more sense to me.
I think the change from #658 should be reverted (with E2E tests to ensure bumping to prerelease is still possible when it's specified as the change type), but that would be a breaking change.
