Refactor release workflow to improve Docker image handling and streamline build steps

- Updated the image resolution step to clarify registry and image name handling.
- Replaced the manual Docker login process with the docker/login-action for enhanced security.
- Introduced Docker metadata extraction and updated the build and push steps to utilize the latest actions for better efficiency.
