CI/CD using outdated mergify rules

[Chriscbr]

I looked at the Mergify summary for a PR and the message below was shown, saying our current configuration will stop working after October 21.

‼️ Action Required ‼️

The configuration uses the deprecated commit_message_template attribute of the queue action in one or more pull_request_rules. It must now be used under the queue_rules configuration.
A brownout is planned on September 16th, 2024.
This option will be removed on October 21st, 2024.

This likely requires fixes in both repos where we're using mergify, here and https://github.com/winglang/winglibs
