chore: Update GitHub Actions workflow to improve version retrieval and streamline GPG key management

- Changed the output variable name from 'name' to 'version' for clarity in the version retrieval step.
- Removed the GPG key import step to simplify the workflow and enhance deployment efficiency.
- These changes contribute to a more maintainable and clear GitHub Actions configuration for future releases.
