Remove John's assignments (#35734)

* Remove John's assignments
- replace him in CODEOWNERS
  - also add a few more owners e.g. to consistently include higher-level owners in contained folders
- switch to `reviewers` in dependabot.yml and add dotnet/aspnet-build
  - Dependabot's `assignments` setting doesn't support teams
  - also add configuration for 'release/6.0' submodules

* Use CODEOWNERS for submodule reviewers
- can remove other `reviewers` settings in dependabot.yml as we update CODEOWNERS elsewhere

* !fixup! add docs/

.github/CODEOWNERS
