Install Android SDK Platform android-36 in Dockerfile

[Copilot]

CI fails because cordova requirements android expects platforms;android-36 which isn't provided by the base image or the existing sdkmanager invocation.

• Added "platforms;${ANDROID_PLATFORM_VERSION}" to the sdkmanager install command alongside existing build-tools

ENV CORDOVA_VERSION=12.0.0 \
    CORDOVA_BUILD_TOOLS_VERSION=34.0.0 \
    ANDROID_PLATFORM_VERSION=android-36 \
    ANDROID_HOME=/opt/android

RUN while true; do echo 'y'; sleep 2; done | sdkmanager "build-tools;${CORDOVA_BUILD_TOOLS_VERSION}" "platforms;${ANDROID_PLATFORM_VERSION}" && \
