We could add name if we need prettier output when the workflow is run:

jobs:
  composer-validate:
    runs-on: ubuntu-latest
    strategy:
      fail-fast: false
    steps:
      - uses: actions/checkout@v4

      - name: Create docker network
        run: |
           docker network create frontend

      - name: Composer validate
        run: |
           docker compose run --rm phpfpm composer validate --strict
