[feature request] Add Agentgateway Linux Foundation project

I am not sure the official process to get added as a non-CNCF project but @lukaszgryglicki suggested to open an issue and ping @caniszczyk so doing such.

https://agentgateway.dev/ is a new-ish Linux Foundation project (https://www.linuxfoundation.org/press/linux-foundation-welcomes-agentgateway-project-to-accelerate-ai-agent-adoption-while-maintaining-security-observability-and-governance) which would love to be included in devstats, as its a great tool we have been using in other CNCF projects and missing in agentgateway.

Please let me know if this is possible and if there is anything you need from me to make it work! Thanks!
