[BUG] Environment variable interpolation not remove double quote in value when using environment config array

[afifurrohman-id]

Description

services:
  rdbms1:
    image: postgres:17.2-alpine
    environment:
     # THIS WORKS
      POSTGRES_USER: "${POSTGRES_USER:-foo}"
      POSTGRES_PASSWORD: "${POSTGRES_PASSWORD:-bar}"

  rdbms2:
    image: postgres:17.2-alpine
    environment:
      # THIS FAILS
      - POSTGRES_USER="${POSTGRES_USER:-foo}"
      - POSTGRES_PASSWORD="${POSTGRES_PASSWORD:-bar}"

when using environment config array like in service rdbms2 above, the double quote is not removed after parsing variable value, but when using environment config map doesn't happen

Steps To Reproduce

1. Run:

docker compose -f - up <<EOF
services:
  rdbms1:
    image: postgres:17.2-alpine
    environment:
      POSTGRES_USER: "${POSTGRES_USER:-foo}"
      POSTGRES_PASSWORD: "${POSTGRES_PASSWORD:-bar}"

  rdbms2:
    image: postgres:17.2-alpine
    environment:
      - POSTGRES_USER="${POSTGRES_USER:-foo}"
      - POSTGRES_PASSWORD="${POSTGRES_PASSWORD:-bar}"


EOF

2. You got:

rdbms2-1  | 2024-12-21 08:09:10.069 UTC [35] FATAL:  zero-length delimited identifier at or near """" at character 12
rdbms2-1  | 2024-12-21 08:09:10.069 UTC [35] STATEMENT:  ALTER USER ""foo"" WITH PASSWORD E'"bar"';
rdbms2-1  |
rdbms2-1  | child process exited with exit code 1

service 1 ok, but service 2 fail because the password value have double quote
