docs-util: improvements and fixes to OAS generation (#8855)

- Add to knowledge base summaries for delete-related properties
- Fix long curl examples overflowing the line
- Fix singular / plural usage in some knowledge base descriptions / summaries
- Fix some workflows not picked up
- Remove query params for routes that don't use them.
