A warning is mistakenly shown for the first release of a package

When a package is first released, a warning will be displayed that informs the user that there is no Git tag for that version, and the latest release of the monorepo is instead being used for comparison purposes. This warning is unnecessary and confusing, and there is no need to show it if we know that there are no Git tags whatsoever for the package.

No source file or test is named. Trace the warning path for packages without a Git tag and inspect how the tool distinguishes a package's first release from a missing tag; done means the warning is omitted when the package has no Git tags at all, while remaining for other comparison cases.
