🔥[🐛] Pod install fails when using monorepo structure in bun

## Issue

I have a project set up with bun and a monorepo structure, with the RN expo app in a sub-directory. When working with bun workspaces the package install linker uses an [isolated install strategy](https://bun.sh/docs/runtime/bunfig#install-linker). Modifying the `bunfig.toml` settings to include hoisted linker settings solves the issue, but at the cost of no longer being able to use isolated installs.

```toml
[install]
linker = "hoisted"
```

When `expo prebuild` is run the following failure is seen during the `pod install` phase.

```
⚠️ Something went wrong running `pod install` in the `ios` directory.
Command `pod install` failed.
└─ Cause: Invalid `Podfile` file:
[!] Invalid `RNFBMessaging.podspec` file: No such file or directory @ rb_sysopen - ../app/package.json.

# from [monorepo root]/node_modules/.bun/@react-native-firebase+messaging@23.8.8/node_modules/@react-native-firebase/messaging/RNFBMessaging.podspec:3
# -------------------------------------------
# package = JSON.parse(File.read(File.join(__dir__, 'package.json')))
> appPackage = JSON.parse(File.read(File.join('..', 'app', 'package.json')))
#
# -------------------------------------------
.

# from [monorepo root]/apps/[subdirectory]/ios/Podfile:49
# -------------------------------------------
# # @generated end react-native-maps
> config = use_native_modules!(config_command)
#
# -------------------------------------------
```

I believe this is due to the linking present between the node_modules folder in the app directory and the root directory. The `appPackage` file can't be located due to the relative path used to resolve the location of the file.

I would include this, but I'm using expo and bun, and the result of that command is somewhat broken with this combo.
