fix: Depend on the stable releases instead of the dev branches

Problem/Motivation

cucumber_demos 12.0.0 pins drupal/cucumber_core and drupal/cucumber_recipes to 12.0.x-dev and sets minimum-stability: dev, so installing the stable release pulls moving dev branches; composer refuses to resolve at default stability with "drupal/cucumber_demos 12.0.0 requires drupal/cucumber_core 12.0.x-dev ... does not match your minimum-stability".

Steps to reproduce

composer require 'drupal/cucumber_demos:^12.0' on a project with default minimum-stability.

Proposed resolution

Move the drupal/cucumber_core and drupal/cucumber_recipes constraints to ~12.0 (matching how drupal/webpatches: ~12.0 is already written) and drop minimum-stability: dev where nothing else needs it.
