ci(build): Add retry logic to desktop build workflow

This commit introduces a retry mechanism to the Gradle build commands in the `build-desktop-platforms.yml` GitHub Actions workflow. This is intended to improve the reliability of the build process by automatically retrying failed packaging tasks up to three times with an exponential backoff.

Key changes:
- A `retry` shell function has been added to the Windows, macOS, and Linux build jobs.
- The `packageExe`, `packageMsi`, `packageDmg`, `packagePkg`, `packageDeb`, and `packageRpm` Gradle tasks now use this retry logic.
- The `--no-daemon` flag has been added to the Gradle commands to prevent potential build conflicts.
- The `AppImage` packaging and upload steps have been removed from the Linux build job.
