`noto upgrade` should prefer stable releases over prerelease versions

[snelusha]

The noto upgrade command should upgrade from prerelease versions to their corresponding stable releases when available.

For example, when running noto upgade on version 1.3.4-beta-5, if stable version 1.3.4 is available, the command should update to 1.3.4 instead of remaining on the prerelease version.
