fix: 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.

Customizes the webpack configurations to keep the class name for
'AbortSignal' as this is the one failing the check.
