fix(bindings): fix ESM errors in Node bindings

1. The module tries to call the native binary as a function.

Only `node-gyp-build` returns a function, so the call is moved there.

2. `node-types.json` is imported with outdated syntax.

Use import attributes which require Node 18.

3. The test does not properly catch import errors.

This is solved by moving the import inside the assertion.
