refactor(AppUpdater): streamline release version fetching and improve update logic (#9167)

- Renamed method from _getPreReleaseVersionFromGithub to _getReleaseVersionFromGithub for clarity.
- Enhanced logic to check for the latest release version using semver.
- Removed unnecessary checks related to test plans when updates are not available.
- Improved logging for better traceability of release version fetching.
