electron-webpack issue on --env.production parameter

* **Version**:
@expo/electron-adapter": "0.0.55"
electron: "13.1.2"
electron-builder: "22.11.7"

No electron-updater used

* **Target**:
Mac, Win and Linux (same issue)

When attempting to build for Mac/Win/Linux , the electron-webpack somehow does not handle the absence of the --env.production parameter that from my scripts is not even explicitly declared

Commenting the lines in the screenshot solves the problem and allows me to build on all platforms
Below the command that I execute to start the build

`build-electron: yarn build-deps && yarn electron-webpack && yarn electron-builder -mwl --dir -c.compression=store -c.mac.identity=null`
The command above follows (as far as I'm aware) the guidelines provided by expo for the correct integration with electron

Thanks Guys!
