Closing this PR due to issues:

1. Empty PR description: The description just says "{pull request content here}" with no explanation.

2. Duplicate of existing PR: PR [FEATURE]: Add Snap packaging support with Github workflow #1998 from x15sr71 already implements Snap packaging support and is under review. That PR was submitted earlier and has received feedback about build issues (libgpac-dev not available in core22).

3. No differentiation: This PR doesn't address the known issues with the existing Snap PR or explain how it differs.

Please check for existing PRs before submitting duplicates. If you want to help with Snap support, consider contributing to PR #1998 instead.
