document onboarded upstream trees
The onboarded upstream trees lack process and documentation. Info we would like to have is:
- why it was onboarded, who is responsible
- pointers to any emails, ML posts, etc
AC:
- add a documentation folder in pipeline-data (!212 (merged))
- add markdown files to it to document the onboarded trees (!212 (merged))
- link the files from the main readme file (!212 (merged))
- integrate the markdown files into the main cki documentation (!213 (merged), !214 (merged), documentation!457 (merged))
- update the documentation about onboarding upstream trees in the documentation repo and in the readme
