Cache is not saved when using cache-dependency-path

[IanVS]

Description:
I'm using a multi-project repo setup, where the top-level of my repo does not have a package.json or a yarn.lock, but subfolders do. I use cache-dependency-path to specify the subfolder, and node dependencies are correctly installed. But then, in the post step, I get the error:

Error: Cache folder path is retrieved for yarn but doesn't exist on disk: undefined

Because it seems that /usr/local/bin/yarn config get cacheFolder is being run at the top level, rather than my subfolder.

Action version:
v2

Platform:

• Ubuntu
• macOS
• Windows

Runner type:

• Hosted
• Self-hosted

Tools version:
yarn 3.1.1

Repro steps:

     - name: Use Node
        uses: actions/setup-node@v2
        with:
          node-version: 16.x
          cache: 'yarn'
          cache-dependency-path: path/to/subdir/yarn.lock

Expected behavior:
Deps should be installed and cached, without failing.

Actual behavior:
The Post Use Node step fails with:

Post job cleanup.
/usr/local/bin/yarn --version

I just found #488, which seems to be related, but maybe not the same issue exactly.

I was able to get this working by explicitly adding cacheFolder in .yarnrc.yml files in both the root and subfolders, but I think that by default the /usr/local/bin/yarn config get cacheFolder should run in the cache-dependency-path to avoid this failure.

Hello @IanVS

I tried to reproduce the issue both with v2 and v3 version of the action but both seems to work without the problem.

Can you please fork the branch and modify the repo to reproduce the issue?
