Verification

All other contributor listings were already properly sorted alphabetically by first name:

• Main README.md maintainers: ✅ (Daniel, Martin, Neville, Ted)
• auto-merge/js/README.md maintainers: ✅ (Amir, Chengzhong, Daniel, Marc)
• auto-merge/js/README.md approvers: ✅ (Gerhard, Haddas, Hector, Jamie, Martin, Matthew, Naseem, Neville, Purvi, Svetlana)

No CONTRIBUTING.md files contained contributor listings that needed sorting.

Fixes #9.
