Create auto-extract-steps-from-codemagic-yaml.py

[odemolliens]

This script extracts script steps defined with anchors from a codemagic.yaml file
and exports each as a separate step.yml file in structured subfolders.
Usage:

1. Place this script in the same directory as your codemagic.yaml.
2. Ensure your codemagic.yaml contains script steps with anchors (e.g. - &build_step).
3. Run the script with Python: python auto-extract-steps-from-codemagic-yaml.py.
4. For each anchored step, a folder will be created at: steps_to_export/<anchor_name>/codemagic/step.yml.
   Each step.yml will include:

• The name of the step
• A fixed ignore_failure: true field
• The script content from the original YAML
  Requirements:
• Python 3
• PyYAML (pip install pyyaml)
