Cache for downloaded installers

[boozook]

We need some caching for installers (pkg/zip).

Documentation

Imho, the easiest way is to do not integrate any cache, but just add following:

• input "installer-path"
• input option "install my installer or just check and maybe install it"
• outputs "installer path" and "installer hash" (version of sdk already in outputs)

So users can use actions/cache@v3 for example with this action and reuse installers. But needed better solution for windows 🤷🏻‍♂️.

I can just use cache as step as like there.
