chore(ci): Run Playwright image build on PRs, verify version consistency

- Trigger the build workflow on PRs that change the Dockerfile, Playwright
  version, or any e2e test application package.json
- Add a version consistency check that verifies all packages and e2e test
  applications use the same @playwright/test version as the canonical
  source (dev-packages/browser-integration-tests)
- On PRs, the image is built (to verify the Dockerfile) but not pushed
- On push to develop and workflow_dispatch, the image is built and pushed
