. You can run it manually with `curl -sL -O https://raw.githubusercontent.com/ddev/ddev/master/cmd/ddev/cmd/scripts/test_ddev.sh && bash test_ddev.sh`

Expected Behavior

When starting up the container set, the network MTU for the projects network is set according to .ddev/.ddev-docker-compose-full.yaml:

networks:
    ddev_default:
        external: true
        name: ddev_default
    default:
        driver_opts:
            com.docker.network.driver.mtu: "1440"
        name: ddev-magento2-sample-project-ddev_default

Actual Behavior

Due to #5533, the compose file is not used for network creation. This results in:

$ docker inspect ddev-magento2-sample-project-ddev_default
[
    {
        "Name": "ddev-magento2-sample-project-ddev_default",
        "Id": "827ddf18a29e22d799984b2887fc8a0e47996ae0a189ab86eb7444041773bd0e",
        "Created": "2023-12-08T17:44:47.771681086Z",
        "Scope": "local",
        "Driver": "bridge",
...
        "Options": {},
        "Labels": {
            "com.ddev.platform": "ddev",
            "com.docker.compose.network": "default",
            "com.docker.compose.project": "ddev-magento2-sample-project-ddev",
            "com.docker.compose.version": "2.23.3"
        }
    }
]

As you can see, the MTU option is missing.

Steps To Reproduce

• Setup any DDEV project in Gitpod with DDEV's workspace image ddev/ddev-gitpod-base:20231127
• Startup the container set
• Run docker inspect <network-name>

Anything else?
