feat: validate version format in auto-updater and release workflow

- Added a check in the desktop release workflow to ensure version tags follow semantic versioning (semver) format.
- Enhanced the auto-updater to log a message and skip updates if the app version is not valid semver.
- Improved type definitions for event handlers in the auto-updater for better TypeScript support.
