[PM-32266] Sideloaded IPA shows error message

### Steps To Reproduce

1. Download the ipa.zip of the newest release
2. unzip it
3. Install the ipa file with an app of your preference using an apple developer certificate (Feather in my case)

### Expected Result

The app installs like any other app I sideloaded without any problems

### Actual Result

The app fails to install with an error when opening the app: “This app could not be installed because its integrity could not be verified”. I tried it multiple times, always the same result. Only for the bitwarden app, not for other ipa files.

### Issue Tracking Info

- [x] I understand that work is tracked outside of Github. A PR will be linked to this issue should one be opened to address it, but Bitwarden doesn't use fields like "assigned", "milestone", or "project" to track progress.

No source file, test, or entry point is named. Start by reproducing the newest-release IPA installation failure on the listed iPadOS environment and inspect the iOS release and signing configuration; done means the IPA installs and launches without the integrity-verification error.
