Is your feature request related to a problem? Please describe it

I hope nest will migrate to ESM modules and would like to ask about the specific migration planning。

Describe the solution you'd like

The default example uses esm

Teachability, documentation, adoption, migration strategy

The default example uses esm

What is the motivation / use case for changing the behavior?

When I write the test file, await import(pathToFileURL(this.dbConfig).href) is not supported. I want to be able to migrate ESM modules. To get top-level support for import()，And ESM is backward compatible with commonjs, which is very friendly.
