Docker compose warning for `version`

[l3ender]

Describe the bug

When using the docker-compose.yml example provided in the repo, Docker issues a warning for use of version:

-> docker compose -f docker-compose.yml up
WARN[0000] /Users/me/repos/myapp/docker-compose.yml: the attribute `version` is obsolete, it will be ignored, please remove it to avoid potential confusion

To Reproduce
A simple compose file like this shows the issue:

version: "3"

services:
  azclicredsproxy:
    image: workleap/azure-cli-credentials-proxy:latest
    ports:
      - "8080:8080"
    volumes:
      - "${HOME}/.azure:/app/.azure/"

Expected behavior

This appears to be a deprecated field in Docker, so it can be removed.

Environment (please complete the following information):

• OS: macOS 15.4
• Docker: version 28.0.4, build b8034c0
