Issue Description

eslint-plugin-unicorn since version 57 deprecated the old config name for use in flat config: https://github.com/sindresorhus/eslint-plugin-unicorn/blob/v57.0.0/index.d.ts#L8-L12

TypeScript reports this, but the no-deprecated rule does not work in eslint.config.ts for the deprecated config name.
