test(node): Relax an assertion

ORT's Npm integration maps Npm's error output to a set of issues. In
case of a malformed `package.json`, this yields a single issue with the
currently used Npm version. A more recent Npm versions, 10.1.0, yields
two issues. Also the wording of the issue to be matched slightly
differs.

So, relax the test assertion such that it does not break when upgrading
Npm to 10.1.0 which is needed in order to upgrade Node to version 20.
