Error using cache in v3.8.0

[ebresson]

Description:
In the last 12 hours we've started getting the following error on the post setup:

Cache folder paths are not retrieved for pnpm with cache-dependency-path = 

This seems to coincide with the release of v3.8.0 of the action.

Action version:
3.8.0

Platform:

• Ubuntu
• macOS
• Windows

Runner type:

• Hosted
• Self-hosted

Tools version:
pnpm 9.6.7

Repro steps:
Use setup-node@v3 with caching enabled:

    - name: Set up node
      uses: actions/setup-node@v3
      with:
        node-version: 18.17.0
        cache: pnpm

Expected behavior:
Post step to complete successfully

Actual behavior:
Getting the following error on the post setup:

Cache folder paths are not retrieved for pnpm with cache-dependency-path = 

Workarounds

1. Removing the cache setting
2. Pinning to v3.7.0 of setup-node

Hopefully this makes sense 😃

For some reason I could not see #828 until I posted this.
