test(cloudflare): add example astro package

[anonrig]

Added a github workflow with missing properties:

      - name: Publish to Cloudflare Pages
        uses: cloudflare/pages-action@v1
        if: steps.cache_built_packages.outputs.cache-hit == ''
        with:
          apiToken: ${{ secrets.CLOUDFLARE_API_TOKEN }}
          accountId: ${{ secrets.CLOUDFLARE_ACCOUNT_ID }}
          projectName: ${{ secrets.CLOUDFLARE_PROJECT_NAME }}
          directory: build
          gitHubToken: ${{ secrets.GITHUB_TOKEN }}
          workingDirectory: dev-packages/env-tests/cloudflare-astro

General question: Is there a reason for making this its own workflow vs adding a job in our build.yml one?

Awesome, thanks for adding this and for figuring out the resolution problems! We can also use this test app for some actual e2e tests later on so it's really valuable to have!
