setup-ruby: Restoring bundler cache is not working in v1.144.1

Ensure the following before filing this issue

• I verified it reproduces with the latest version with - uses: ruby/setup-ruby@v1 (see Versioning policy)

• I tried to reproduce the issue locally by following the workflow steps (including all commands done by ruby/setup-ruby, except for Downloading Ruby & Extracting Ruby), and it did not reproduce locally (if it does reproduce locally, it’s not a ruby/setup-ruby issue)

Are you running on a GitHub-hosted runner or a self-hosted runner?

### Any other notes?

Everything worked fine with `v1.144.0` but starting with `v1.144.1` `ruby/setup-ruby` fails to restore the bundler cache. There's no error message. The cache is just not restored.

I suspect the issue is this PR: https://github.com/ruby/setup-ruby/pull/482. It updated the NPM package `@actions/cache` from `3.0.6` to `3.2.1`. [3.2.1](https://github.com/actions/cache/releases/tag/v3.2.1) introduced this change: https://github.com/actions/cache/pull/1039, which was reverted in the next version [3.2.2](https://github.com/actions/cache/releases/tag/v3.2.2) in https://github.com/actions/cache/pull/1049.
