"dependency path is undefined" errors after upgrade to electron-builder 26

[panther7]

We have similar issue like #9006 with dependency path is undefined, becase project has node_modules in root folder, but "build" folder is without node_modules.
Posible solution is define path for node_modules, like this https://www.electron.build/app-builder-lib.interface.metadatadirectories

Example:

.
├── node_modules
└── dist
    └── app.html

Works perfectly in electron-builder 25.

@panther7 would you be willing to share a minimum repro repo for us to create a unit test from?

@beyondkmp can you please take a look at this?

[panther7]

@mmaietta simple test case added to first desc.
