[RolandJentschETAS]

This pull request updates the documentation for the recommended folder structure of a module repository, making it more comprehensive and aligned with modern development practices. The main improvements include the addition of CI/CD configuration folders, new documentation requirements for safety and security analyses, and expanded structure for component-level documentation and build files.

Folder structure and configuration updates:

• Added .github/workflows directory to the recommended structure for CI/CD pipeline configuration. [1] [2]
• Added MODULE.bazel, BUILD, and project_config.bzl files for Bazel build system integration. [1] [2]

Documentation and compliance enhancements:

• Expanded requirements for safety and security analysis documentation at both feature and component levels, including new references such as [:need:wp__requirements_feat_aou] and [:need:wp__requirements_comp_aou]. [1] [2] [3] [4]
• Updated component-level documentation structure to require additional architectural verification and component classification for pre-existing software. [1] [2]

These changes help ensure that repositories are better organized, CI/CD ready, and compliant with safety and security documentation standards.
