feat!: use 'commonjs-import' as CJS external type by default

[fi3ework]

Summary

It's hard to cover all cases of whether it's under node 13.2.0 without calling Browserslist API. Since Node 13.2 has reach EOL for years (https://endoflife.date/nodejs). I think it's fine to set commonjs-import as the default external type for Node.js and demonstrate the differences between the externals type on library build scenario next.

Also bump Rsbuild to ~1.1.4

Done.

TODO: don't merge this until Rsbuild has relaid on @rspack/core 1.1.2. It strictly requires at least 1.1.3 version of Rsbuild (assume that Rsbuild will bump @rspack/core on 1.1.3). We need to change the dependent Rsbuild version to ^1.1.3 alongside.
