Fixed

• Changed bump to reset lower version numbers.
  • If v1.1.1, major +1 will become => v2.0.0 (not v2.1.1).
  • If v1.1.1, minor +1 will become => v1.2.0 (not v1.2.1).
  • Patch +1 will continue to work the same.
  • It's debatable whether this is a fix or a change, but I'm labeling it as a fix, as this way is more usable and expected.
  • I debated whether to also drop off the pre-release and build-metadata, but it's a hard decision. Even though the version changed, maybe it's still a pre-release and/or still needs the same build-metadata. You could argue that bumping the major version should always drop it off, but I'm not sure. For now, they are unaffected by this change. In the future, major (only) +1 might also drop pre-release & build-metadata.
