fix: make is-builtin-module also support CJS + work with non-standard names

[MeLlamoPablo]

This PR fixes two issues in the is-builtin-module codemod:

1. It doesn't work with non-standard import names. If you imported it like this:

   import banana from 'is-builtin-module';

   The codemod would replace it with:

   import { isBuiltin } from "node:module";

   But it wouldn't update the usages of the package, staying as banana. I've added a fixture under case-2 to handle this.

2. It doesn't work with CJS. If used with a require call it would simply do nothing.

   I've added a fixture under case-3 to test that.
