[BUG] Docker Compose pull fails when a required env_file is missing

[KostaGorod]

Description

I Believe this is part of previous requests https://github.com/docker/compose/issues/1973 & https://github.com/docker/compose/issues/9181.

which defines that some commands don't need to validate full config.

my issue that when I pull images, using env_file with required=true. the pull fails due to missing env file.

My expectation is that the required is part of running the compose (and validating), not pulling. If there is situation that env_file is expected as part of pull (which I'm not aware of such situations), I would expect option to declare that its required only for commands such up but ignored for pull. for example required: "runtime"

Steps To Reproduce

1. add to docker-compose.yml

env_file:
  - path: .myservice.env
    required: true

2. run docker compose pull
3. command fails due to missing file. - undesired behavior
4. edit to required: false
5. command succeeded.
6. but now docker compose up ignores missing file as well
