refactor: enhance deploy_preview.sh for idempotent Helm repo addition… (#41043)
… and plugin management

### Changes Made
- Updated Helm repo addition to be idempotent, preventing errors if the
repo is already added.
- Added logic to check for the existence of the mapkubeapis plugin
before attempting installation, improving script robustness.
- Enhanced error handling for optional commands to ensure the deployment
process continues smoothly even if certain steps fail.

These improvements streamline the deployment process and enhance the
reliability of the script.
