fix: support scanoss bundling

scanoss depends on node-fetch <3. node-fetch in that version fails their
instance checks, as it relies on constructor/class names which are
removed by the backend bundling.

Adjusts the generated webpack configuration to keep the class name for
AbortSignal as this is the name checked in node-fetch.
