[BUG] config --no-interpolate with default values

[jprince14]

Description

There is a bug with docker compose config --no-interpolate that is seen when variables have default values.

Steps To Reproduce

Using this config as an example

services:
  client:
    image: hello-world
    volumes:
      - /tmp:/tmp/${BUG_HERE:-DEFAULT}/path
      - /tmp:/tmp/${WORKS_AS_EXPECTED}/path

When I call docker compose config everything works as expected, the volumes I see are

    volumes:
      - type: bind
        source: /tmp
        target: /tmp/DEFAULT/path
        bind:
          create_host_path: true
      - type: bind
        source: /tmp
        target: /tmp/path
        bind:
          create_host_path: true

The bug occurs when i call docker compose config --no-interpolate, There is an issues with the volume that contains the default value

    volumes:
      - bind:
          create_host_path: true
        source: /tmp
        target: /tmp/${BUG_HERE
        type: bind
      - bind:
          create_host_path: true
        source: /tmp
        target: /tmp/${WORKS_AS_EXPECTED}/path
        type: bind

The output I was expecting to see from docker compose config --no-interpolate is

    volumes:
      - bind:
          create_host_path: true
        source: /tmp
        target: /tmp/${BUG_HERE:-DEFAULT}/path
        type: bind
      - bind:
          create_host_path: true
        source: /tmp
        target: /tmp/${WORKS_AS_EXPECTED}/path
        type: bind
