Implement command `psdk-cli version`

[AerunDev]

Description

As a user, I want to know the installed CLI version and the default PSDK version, so I can verify compatibility.

Acceptance criteria

• psdk-cli version displays the CLI version.
• The command shows the currently used PSDK version (if available).
• If no local PSDK is found, an explicit message is shown.

One little issue with If no local PSDK is found, an explicit message is shown.

I handled the case when we are inside a project, but when we're outside of a project, it just shows nothing because there's no project so there's no reason to have a local psdk version. Would that behaviour be correct?

Maybe fallback to the local Pokémon Studio's PSDK version or display a message if there is no such folder? (Case of psdk-cli installed on a project that do not use Studio)

No, my question is when you're using the psdk-cli outside of a project, for example, inside a plugin. Current behaviour is not showing anything about project's PSDK version. I'm asking if that's OK.

I might have made a mistake with the Studio's PSDK version (because of the configuration file story), I forgot that we could simply clone pokemonsdk and make it the global version :s

It's OK to me!
