[JoshuaKGoldberg]

Tooling Report Checklist

• I have tried restarting my IDE and the issue persists.
• I have pulled the latest main branch of the repository.
• I have searched for related issues and found none that matched my issue.

Overview

Currently open, failing PRs:

• docs: add astrochemx as a contributor for code #2070
• docs: add birkskyum as a contributor for ideas #2163
• docs: add michaelfaith as a contributor for ideas #2187

#2187 has an example of a big integration test snapshot failure:

 ❯ src/integration.test.ts:129:4
    127|  expect(
    128|   diffCreatedDirectory(actual, created.files, processText),
    129|  ).toBeUndefined();
       |    ^
    130| });
    131| 

The issue is roughly around the integration test keeping a snapshot of contributors data in the .all-contributorsrc and/or README.md files.
