Fails when Docker is not running

[tisto]

When running cookiecutter-plone-starter without Docker daemon running it fails:

pipx run cookiecutter gh:collective/cookiecutter-plone-starter
⚠️  cookiecutter is already on your PATH and installed at
    /opt/homebrew/bin/cookiecutter. Downloading and running anyway.
You've downloaded /Users/timo/.cookiecutters/cookiecutter-plone-starter before. Is
it okay to delete and re-download it? [y/n] (y): y

Plone Distribution EDU (Frontend) generation
--------------------------------------------------------------------------------

Summary:
  - Plone version: 6.0.10
  - Volto version: 18.0.0-alpha.18
  - Volto Generator version: 9.0.0-alpha.9
  - Output folder: /Users/timo/workspace/plone/plone-distribution-edu-frontend

Frontend codebase:
 - Installing required npm packages
 - Generate frontend application with @plone/volto 18.0.0-alpha.18

Backend codebase
 - Remove folder src/plone_distribution_edu_frontend/src/plone_distribution_edu_frontend/tests not used by pytest
 - Format generated code in the backend

Error while running ['make', 'format']:
docker: Cannot connect to the Docker daemon at unix:///Users/timo/.docker/run/docker.sock. Is the docker daemon running?.
See 'docker run --help'.
make: *** [format] Error 125

ERROR: Stopping generation because post_gen_project hook script didn't exit successfully
Hook script failed (exit status: 1)
➜  plone ls

It would be super nice if there would be a check up-front that checks if Docker is running or if cookiecutter would not fail but wait for you to start docker.
