test: pass data into napi_create_external

Since v8 10.1 v8::External::New DCHECKs that the data passed
into it cannot be a nullptr because that's not serializable
as external references. This updates the test to pass a
dummy data pointer to the call - which does not matter for the
test since we only care about whether the finalizer is
called.
