When you upgrade to ESLint 10.14, if you have an .eslintrc and .eslintignore files, you get an error message telling you that .eslintignore is not supported, and a URL to their migration guide.
When you go to the migration guide, it tells you that you can create an .eslintignore file, or add ignorePatterns to your .eslintrc.
I'm so tired of everything being internally-inconsistent slop.
