[request] output paths

[ReenigneArcher]

Description:
Please add outputs to the action, such as npm-path. The setup-python action does this: https://github.com/actions/setup-python/blob/f677139bbe7f9c59b41e40162b753c062f5d49a3/action.yml#L34

At a minimum, printing the locations to the log would be helpful.

Justification:
I need to provide the npm path to CMake and this would make it convenient as it requires a full path.

Are you willing to submit a PR?

Yes, but I'm not familiar with the code base.

Hello @ReenigneArcher 👋,
Thank you for this feature request. We will investigate it and get back to you as soon as we have some feedback.

I would also like this. my user can't even execute node -v after the install as the PATH is not updated apparently...

I had the setup and usage in two different jobs, so the PATH was replaced. would still like to see it output for usage in future pipelines
