Disallow `import` declarations which import extraneous modules (`n/no-extraneous-import`)

💼 This rule is enabled in the following configs: ☑️ flat/recommended, 🟢 flat/recommended-module, ✅ flat/recommended-script, ☑️ recommended, 🟢 recommended-module, ✅ recommended-script.

If an import declaration's source is extraneous (it's not written in package.json), the program works in local, but will not work after dependencies are re-installed. It will cause troubles to your team/contributors. This rule disallows import declarations of extraneous modules.
