@actions/artifact as part of the github-script

[y-nk]

Is your feature request related to a problem? Please describe.
I'm always frustrated by the arbitrary choice of libraries included/not-included in the github-script action.

Describe the solution you'd like
add all the @actions/* npm packages, or make it configurable which are preinstalled and linked with a with option (default as now, so no breaking change)

Describe alternatives you've considered
using npm install but this really kills the conveniency of this action. at this point i can just npm install @actions/core @actions/github etc etc..., so it's better not to do it.

This was previously discussed in #120

For packages like @actions/cache and @actions/artifact, I would expect a fair bit of code to use those fully and would be better off used in their own action.

There's also the concern about drastically increasing the size of this action, which slows down every run using actions/github-script even if the additional libraries aren't used.

fair point. thanks for your feedback and linking with #120 🙏
