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.

Inizia tracciando come viene interpretato l’input ruby-version nei file di workflow di GitHub Actions, usando come caso motivante l’esempio riportato del valore d’ambiente 3.0. Definisci e verifica i significati previsti di 3, 3.0 e 3.x, incluso l’impatto sulla compatibilità dei workflow esistenti.
