android: patch RN settings.gradle.kts /tmp projectDir for Windows

The Windows unit-test lane failed configuring the React Native build-from-
source composite build:

    Configuring project ':packages:react-native' without an existing directory
    is not allowed. The configured projectDirectory '...\react-native\tmp'
    does not exist

React Native's own settings.gradle.kts declares the intermediate container
projects :packages and :packages:react-native with projectDir = file("/tmp"),
purely to satisfy Gradle 9's rule that every project in a path have an existing
folder. "/tmp" exists on the posix CI hosts but on Windows it is not an
absolute path, so Gradle resolves it to a non-existent <react-native>\tmp and
the build fails before any task runs. This is why only windows-latest was red
while ubuntu and macOS passed.

Add a pnpm patch replacing file("/tmp") with
file(System.getProperty("java.io.tmpdir", "/tmp")): the JVM temp dir is "/tmp"
on posix and %TEMP% on Windows, both of which always exist. Remove the patch
once React Native stops hardcoding "/tmp" upstream.
