Makefile changes to update version information

Adding a change to make it easier to update version information in `go`, `YAML`, `Makefile`, and `README` files.
Automatically run this when creating a binary or when creating images.

The version information is stored in `hack/VERSION`, and should be updated to reflect the new version information at the time of the release.
