Add version attribute as action output

[Poeschl]

During using the information addon, I was missing the version attribute. This PR adds it as additional output.

I can see this being helpful for some add-ons structures, but in a CI/CD automated environment, it doesn't make much sense to me.

Versions should be defined by things like releases or git tags.

I will use it as tags for my addons which is indeed not a good practice for releasing them. Since its still a freetime-project I have currently no motivation to come up with a complex release structure or splitted add-on repositories.

The version is also an basic attribute of an addon as well which could be used also in CI. Thinking about checks of matching versions of Changelog and config.json and automatic tag creation on master pushes.

👍

But needs adjustments to the README/documentation.

Will do this evening. What exactly do you address @frenck ?

[Poeschl]

Ah, forget the comment before ;)
