Cache does not seem to be working with use-installer: true

Hi 👋

I don't see a cache being created for SAM under the GitHub Action Caches in my repository using this action.

I'm using:

    runs-on: ubuntu-latest
    steps:
      - uses: aws-actions/setup-sam@v2
        with:
          use-installer: true
          version: 1.107.0

and my workflow run logs constantly show:

Cached AWS SAM CLI 1.107.0 to /opt/hostedtoolcache/sam/1.107.0/x64

Look like the @actions/cache module with the restoreCache and saveCache functions should be used, instead of @actions/tool-cache with find and cacheDir, in order to actually persistently cache the files.
