[fix] eslint: migrate JSON config to flat-config (.eslintrc.json -> eslint.config.js)dependabot/npm_and_yarn/searx/static/themes/simple/master/grunt-eslint-25.0.0

In ESLint v9.0.0, ``eslint.config.js`` is the new default configuration
format. The previous format, ``eslintrc``, is now deprecated and will not
automatically be searched for. [1]

This migration was done with the help of the "Configuration Migration Guide" [2]
