[BUG] Incorrect warning about secrets from environment variable being ignored

[qhaas]

Description

While it is known that file secrets cannot have their ownership / permissions set via service level secrets, it appears that environment secrets can, yet the warning about said ownership / permissions being ignored is displayed.

Steps To Reproduce

1. Set a secret from an environment variable and attempt to modify its uid, gid, and mode via service-level secrets

$ cat compose.yml 
services:
  my-service:
    image: busybox:stable
    command: ls -ln /run/secrets/my-secret
    secrets:
      - source: my-secret
        uid: "10"
        gid: "20"
        mode: 0754
secrets:
  my-secret:
    environment: MY_SECRET

2. Run docker compose and display the uid, gid, and mode of the secret, noting the incorrect warning about them not being set

$ MY_SECRET=success docker compose run --rm my-service
WARN[0000] secrets `uid`, `gid` and `mode` are not supported, they will be ignored 
-rwxr-xr--    1 10       20               7 Jul 23 20:40 /run/secrets/my-secret
