`group_add` unavailable when using `docker stack deploy`

Description

Docker stack deploy produces an Additional property ... is not allowed error when running with a compose file that contains the group_add property.

Reproduce

1. Create docker-compose.yaml file with group_add property in a service

version: "3.8"
  
services:
  mysql:
    image: arm64v8/mysql:8-oracle
    group_add:
      - "15000"
    environment:
      MYSQL_ROOT_PASSWORD: ${MYSQL_ROOT_PASSWORD:-root}
      MYSQL_DATABASE: ${MYSQL_DATABASE:-test_db}
      MYSQL_USER: ${MYSQL_USER:-user}
      MYSQL_PASSWORD: ${MYSQL_PASSWORD:-password}
    ports:
      - target: 3306
        published: 3306
        protocol: tcp
        mode: host

2. Run docker stack deploy -c docker-compose.yaml
3. services.mysql Additional property group_add is not allowed is produced

Expected behavior

docker stack deploy should deploy the service with the group_add property.

Additional Info

No response

Start by reproducing the reported validation failure with the provided compose file and docker stack deploy command, then trace the stack-deploy CLI path that validates service properties. Confirm the change by rerunning the reproduction and verifying that a service using group_add deploys successfully without the Additional property error.
