build(release): improve artifact handling robustness and logging

Update find commands for AppImage updater artifacts to use more generic wildcards.
Configure `action-gh-release` to not fail on unmatched files.
Set `actions/upload-artifact` to warn if signature files are not found.
Enhance log messages for artifact preparation steps.

These changes make artifact matching more resilient to filename variations.
They prevent the release workflow from failing if optional artifacts are missing.
Improved logging provides clearer feedback during artifact preparation.
