[Request] Enable Immutable Releases

[jkylekelly]

👋 Hi there!

We're the Package Security team at GitHub. We recently staff shipped immutable releases, a feature designed to improve supply chain security by preventing modifications to published releases.

We noticed that CopilotForXcode is actively using GitHub Releases, and wanted to ask if you'd consider enabling immutability for your releases. This can be done with a simple checkbox in your repository's Settings > General > Enable release immutability.

If you have any concerns, blockers, or reasons for not enabling this feature, we'd love to hear about them! Your feedback helps us better understand real-world needs and improve our offerings.

For more details or discussion, please see: https://github.com/github/security-products/discussions/1883

Thanks for helping keep the ecosystem secure!
