App sandbox not enabled

**Describe the bug**
I am unable to produce a package for MAS upload that will pass validation in transporter.

Asset validation failed (90296)
App sandbox not enabled. The following executables must include the "com.apple.security.app-sandbox" entitlement with a Boolean value of true in the entitlements property list: [(
".../Frameworks/Electron Framework.framework/Versions/A/Helpers/chrome_crashpad_handler",
"../Frameworks/Squirrel.framework/Versions/A/Resources/ShipIt",
"../Frameworks/xxxyyyyyxxxxx Helper (GPU).app/Contents/MacOS/xxxyyyyyxxxxx Helper (GPU)",
"../Frameworks/xxxyyyyyxxxxx Helper (Plugin).app/Contents/MacOS/xxxyyyyyxxxxx Helper (Plugin)",
"../Frameworks/xxxyyyyyxxxxx Helper (Renderer).app/Contents/MacOS/xxxyyyyyxxxxx Helper (Renderer)",
"../Frameworks/xxxyyyyyxxxxx Helper.app/Contents/MacOS/xxxyyyyyxxxxx Helper",
"../xxxyyyyyxxxxx.app/Contents/MacOS/xxxyyyyyxxxxx" )]

**To Reproduce**
Steps to reproduce the behavior:

1. Create new electron project
2. cd electron && npm run electron:build-mac
3. Upload pkg to transporter

**Screenshots**

**Desktop (please complete the following information):**
- Device: 2021 iMac (m1)
- OS: Mac OS 12.5

Start with the `npm run electron:build-mac` entry point and inspect how the generated package and entitlements property lists are produced for the listed executables. Reproduce the build on macOS, then upload the resulting package to Transporter; done means validation no longer reports missing `com.apple.security.app-sandbox` entitlements.
