CI/CD Build & Push ECR

This GitHub Actions workflow automates the process of building and pushing a Docker image to Amazon Elastic Container Registry (ECR). It checks out the repository, configures AWS credentials, logs in to ECR, builds the image, and tags it for pushing. Perfect for streamlining Docker deployments!
