Monorepo config support

[ishan-sharma-me]

Behavior

• Turbo monorepo using pnpm. node_modules are in the root directory, react-native project is in apps directory of the root directory.
• Set up everything according to the instructions and changed the pre-actions script to point the node_modules

$NODE_BINARY "${SRCROOT}/../../../node_modules/react-native-keys/keysIOS.js"

• build works but the tmp.xcconfig is generated in a ios folder in the root folder whereas it should be generated in apps/react-native-project/ios folder.
• I think just exposing some env variable we can set in the pre-actions script will solve this

Platform

• Android
• iOS

Did you find any solution ???

I made a couple of edits to RNKeys.gradle to get this to work.

Digging into RNKeys.gradle it looks like there's two paths for fetching the key file -- one for RNKeys.gradle and another for keysAndroid.js

The one in RNKeys.gradle looks from {workspace root}/{react native app}/android/../${keyfile}
The one in keysAndroid.js looks from {workspace root}/ -- monorepo bug.

Added this custom path for now and modified RNKeys.gradle:
ln 68 + def keyFileMonorepoPathFix = safeExtGet("keyFileMonorepoPathFix", "")
ln 73 - exportCommand = "set KEYSFILE=" + keysFile + " && node ";
ln 73 + exportCommand = "set KEYSFILE=" + keyFileMonorepoPathFix + keysFile + " && node ";

ln 75 - exportCommand = "export KEYSFILE=" + keysFile + " && ";
ln 75 + exportCommand = "export KEYSFILE=" + keyFileMonorepoPathFix + keysFile + " && ";

Then in app build.gradle, after setting the ext.keyFiles I added:
project.ext.keyFileMonorepoPathFix = "{react native app}/"

Not sure if this is the best approach. Ideally would there be checks whether there's a monorepo in RNKeys.gradle and keysAndroid.js? Or something closer to how iOS does it where we can add our own customization per scheme?
