Issue:
Silence the recommendations/hints from Docker Desktop
### Describe the bug

Using Docker, as of late, includes a lot of unhelpful recommendations being printed to the console.

For instance:
```
(venv) user@vm-win11:~/tmp/beeware/helloworld$ briefcase build --target fedora

[Docker] Downloading Docker base image for fedora...
Using default tag: latest
latest: Pulling from library/fedora
8237fce9fd6b: Pull complete
Digest: sha256:06df381d697d14940c886fda8e94a4fdc838df74e93f65111ed3ea04f7a7d6e0
Status: Downloaded newer image for fedora:latest
docker.io/library/fedora:latest

What's Next?
  View a summary of image vulnerabilities and recommendations → docker scout quickview fedora
```

We should disable these given they aren't useful for our use-case.

### Steps to reproduce

Run Docker-related commands with Docker Desktop.

### Expected behavior

Use environment variable `DOCKER_CLI_HINTS=false` to disable this output.

### Screenshots

### Environment
