How about changing interpretation of version string

Many users who wants use 3.0.x write ruby-version: 3.0 by mistake.

3.0 interpreted as 3 on GitHub Actions.

For example, following workflow step prints 3 only.

        env:
          env_var: 3.0
        run: |
          set -x
          echo ${env_var}

So I propose changing the meaning of 3 (and 3.0 on workflow files) use 3.0.x, and 3.x (or something) use latest 3.x.x.

After this change, many users can write 3.0 intentionally, and some (probably less) users who want use latest 3.x.x can write 3.x or something instead.

Commencez par retracer comment l’entrée ruby-version est interprétée dans les fichiers de workflow GitHub Actions, en prenant comme cas motivant l’exemple signalé de valeur d’environnement 3.0. Définissez et vérifiez les significations attendues de 3, 3.0 et 3.x, y compris l’impact sur la compatibilité des workflows existants.
