Prefer using the `node:` protocol when importing Node.js builtin modules

💼 This rule is enabled in the ✅ recommended config.

🔧 This rule is automatically fixable by the --fix CLI option.

When importing builtin modules, it's better to use the node: protocol as it makes it perfectly clear that the package is a Node.js builtin module.

Note that Node.js support for this feature began in:

v16.0.0, v14.18.0 (require())

v14.13.1, v12.20.0 (import)
