• githubgen: githubgen now injects component lists and others into CODEOWNERS and ALLOWLIST files using magic strings instead of writing the complete files. (#​674)

  This feature allows maintainers to have custom content in addition to the component lists and others in their CODEOWNERS and ALLOWLIST files.
  Magic delimiter strings need to be added to CODEOWNERS and ALLOWLIST files fot githubgen to fill in the content.
  Use # Start/End components list, # Start/End distribution list and # Start/End unmaintained components list in your CODEOWNERS file.
  Use # Start/End deprecated components list and # Start/End unmaintained components list in your ALLOWLIST file.
  Also, issue template files need to be updated and use # Start/End components list to fill in the component list.
