podman: "userns_mode: keep-id" is still needed for Compose-based Dev containers #11934

This was fixed for plain containers: #10798.
The original issue still happens for the Compose-based Dev containers, so it wasn't apparently fixed there too, yet.

Christof Marti (@chrmarti) We probably need the same for https://github.com/devcontainers/cli/blob/main/src/spec-node/dockerCompose.ts so that Compose-based Dev Containers could be covered, too?

Currently, I have to manually add the userns_mode: keep-id workaround to the compose.yaml, so your fix apparently doesn't apply there.
