This pull request updates the GitHub Actions workflow for building and publishing the production Docker image. The workflow is now triggered by a published release instead of a push to the main branch, and it replaces Docker Hub with Quay.io as the image registry. The Docker build and push steps have also been simplified using a different GitHub Action.

Workflow trigger and registry updates:

• Changed workflow trigger from push on the main branch to release events of type published, ensuring production images are built only for official releases.
• Replaced Docker Hub authentication and image publishing with Quay.io, updating credentials and registry settings for the new destination.

Build and deployment process changes:

• Consolidated Docker build and push steps using redhat-actions/push-to-registry@v2, simplifying the workflow and removing separate setup steps for Docker Buildx and Docker login.
