Node.js caching like actions/setup-node

[privatenumber]

Request

When downloading the Node.js version specified in .npmrc#use-node-version, cache the Node.js like actions/setup-node so it can be setup faster next time

Motivation

I would like to migrate from using a .nvmrc file to specify the development Node.js version, to using pnpm's use-node-version.

Currently on GitHub actions, I can configure actions/setup-node to read from .nvmrc, and it will download & cache the Node.js version so it only takes about 3s to setup.

However, when I move to using pnpm with this action, it doesn't seem to cache the downloaded Node.js and it adds about 8s to the pnpm setup:
