google-guest-agent now requires systemd-networkd version 252+, but Ubuntu 22.04.05 only provides 249

[noll_6451]

### Summary
After updating google-guest-agent to version 20241011.01-0ubuntu1~22.04.0, we noticed that systemd-networkd version 252 or higher is now required. However, Ubuntu 22.04.05 LTS(Jammy Jellyfish) provides only version 249 by default, causing a compatibility issue.

### Environment

• VM Image: ubuntu-2204-jammy-v20241119
• google-guest-agent Version: 20241011.01-0ubuntu1~22.04.0
• systemd-networkd Version: 249

### Observed Issue
On boot, google-guest-agent logs the following error:

systemd-networkd version 249 not supported: minimum 252 required

rolling back changes for systemd-networkd

Setting up dhclient
Finished setting up dhclient
Completed adding/removing routes for aliases, forwarded IP and target-instance IPs

This prevents the network from properly initializing, requiring manual intervention.

### Questions

1. What are the specific reasons behind google-guest-agent now requiring systemd-networkd version 252 or higher?
2. Is there an official way to upgrade systemd-networkd on Ubuntu 22.04 to meet this requirement?
3. Will there be any updates to google-guest-agent that address this compatibility issue?

Any guidance on how to proceed would be greatly appreciated.
