Revert incorrect co-author credit

Editor assessment

The subject states the correction exactly: an incorrect co-author credit is reverted. chore is the right type, and the empty scope is tolerable since the subject names the artifact. The body's single line, 'This reverts commit 62ed9712...', is the conventional and fully sufficient explanation, pointing at the exact commit being corrected. No other footer is needed. Wording is compact and clean. A model small-revert message.
