feat: remove is-builtin-module dependency (#970)

* feat: remove is-builtin-module dependency

Node provides a list of built ins via `builtinModules`. We can test
against this rather than including an extra (redundant) dependency.

In future, if we introduce a version constraint of node `>=16`, we can
use `isBuiltin` which node provides:

```ts
import {isBuiltin} from 'node:module';

isBuiltin('fs'); // true
```

* Simplify code
