Does this PR introduce a breaking change?

Potential no, but you can faced with such message:

(node:499534) [MODULE_TYPELESS_PACKAGE_JSON] Warning: Module type of file:///path/to/webpack.config.ts is not specified and it doesn't parse as CommonJS.
Reparsing as ES module because module syntax was detected. This incurs a performance overhead.
To eliminate this warning, add "type": "module" to /home/alexander-akait/IdeaProjects/webpack-cli/package.json.
(Use `node --trace-warnings ...` to show where the warning was created)

it means:

• You webpack.config.ts is in ESM, but your `type: "commonjs"``
• You have babel/esbuild/etc to handle this configuration and before we load these configuration using require
• But now you configuration was loaded by import and built-in typescript support

Nothing critical - just rename your configuration file to `mts``

If relevant, what needs to be documented once your changes are merged or what have you already documented?

Doc site will need to be updated
