provide cache datails as outputs

[sherif-amk]

actions/setup-node should output cache details such as:

• path
• key
• hits: boolean
• size
• last_updated

 steps:
 - name: install NodeJs
 id: node
 uses: actions/setup-node@v3
 with:
 cache: pnpm

 - name: use pnpm cache //<-- may be in another job
 uses: actions/cache
 with:
 path: ${{ step.node.outputs.path }}
 kay: ${{ step.node.outputs.kay }}

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

Hello @sherif-amk👋,
Thanks for the suggestion! setup-node already exposes the relevant cache details as outputs: cache-hit (your hits request), along with cache-primary-key and cache-matched-key (your key request), so reusing the cache key and hit status in a later step or job works today.

As for size and last_updated, these aren't provided by @actions/cache and would require authenticated REST API calls with actions: read permission. That adds complexity and falls outside setup-node's core scope (installing Node.js and restoring caches), so we've decided not to move forward with this enhancement and will be closing it for now.

We really appreciate you taking the time to raise this. Please feel free to reach out if you have any further questions or concerns!
