Code Review

This pull request adds a new flatpak package for 'monkey-bubble'. The configuration is well-structured, but I have a suggestion regarding the source URL. To align with the repository's automated update workflows, the URL should point to the 'latest' artifact rather than a specific version. This ensures that the automated process for updating packages can function correctly.

[gemini-code-assist]

To enable automatic updates, the source URL should point to the 'latest' version of the package. Using a version-specific URL will prevent the automated update workflow from fetching new versions.

References

1. For nightly builds with an automated update workflow that pins artifacts via a hash, use a 'latest' URL to enable automatic updates. A permanent, version-specific URL would break this process.
