Fix for #644, allow configuration of artifact name for Archive receipt step

[wbonnefond]

To ensure the Archive receipt step works when run in a matrixed workflow, the artifact name needs to be unique.

This change adds an input to the action for the artifact name archieveReceiptArtifactName and defaults to the previous hardcoded value. This allows callers to specify the name if needed.

In our usecase, we run this in a matrixed workflow against 8 apps, so we can ensure the name is different by appending the app name to the artifact name like:

- name: Run experiment 1
  uses: gradle/gradle-enterprise-build-validation-scripts/.github/actions/gradle/experiment-1@actions-stable
  env:
    DEVELOCITY_ACCESS_KEY: xxxxxx
  with:
    gitRepo: ${{ env.GIT_REPO }}
    gradleEnterpriseUrl: ${{ env.GRADLE_ENTERPRISE_URL }}
    tasks: ${{ env.TASKS }}
    projectDir: ${{ matrix.target.project }}
    archiveReceiptArtifactName: "experiment-1-receipt-${{ matrix.target.project }}"

Closing as this is being fixed in #648
