I am setting cache to `false` and directly use actions/cache:

    - uses: actions/cache@55cc8345863c7cc4c66a329aec7e433d2d1c52a9 # v6
      if: ${{ inputs.setup-go == 'true' }}
      with:
        path: |
          ${{ env.gocache }}
          ${{ env.gomodcache }}
        key: ${{ runner.os }}-${{ runner.arch }}-go${{ steps.go-setup.outputs.go-version }}-${{ hashFiles('go.sum') }}-${{ env.today }}
        restore-keys: |
          ${{ runner.os }}-${{ runner.arch }}-go${{ steps.go-setup.outputs.go-version }}-${{ hashFiles('go.sum') }}-
          ${{ runner.os }}-${{ runner.arch }}-go${{ steps.go-setup.outputs.go-version }}-

You get one new cache every day, and you can still load the most recent one if you are the first run today.
