Support .cjs file extension when using eslint flat config

[benpsnyder]

Current Behavior

packages/eslint/src/utils/flat-config.ts only supports eslint.config.js

Expected Behavior

packages/eslint/src/utils/flat-config.ts should support eslint.config.js and eslint.config.cjs because when "type": "module" is used in package.json flat config with eslint breaks

I am using bun instead of node and bunx --bun nx run <project>:lint is how I want to execute my linting
