Generally, I support and 👍 this change, but I have another question: why did eslint-plugin-eslint-plugin choose the Node.js version range "^20.19.0 || ^22.13.1 || >=24.0.0"?

https://github.com/eslint-community/eslint-plugin-eslint-plugin/blob/main/package.json#L94

It seems that if someone uses 22.13.0, it won't be supported, since generator-eslint uses the following version range:
