Detect Android SDK using ANDROID_SDK_ROOT env var

Environment

Describe the bug

On running the command ns doctor, I get this message

× The ANDROID_HOME environment variable is not set or it points to a non-existent directory. You will not be able to perform any build-related operations for Android.

However, I have the ANDROID_SDK_ROOT env var set which is equivalent to ANDROID_HOME.

To Reproduce

Run ns doctor

Expected behavior
I expected it to detect the Android SDK using the ANDROID_SDK_ROOT env var.

Sample project

Additional context

https://developer.android.com/studio/command-line/variables#envar

The ANDROID_HOME env var is deprecated. Refer to the link above.

Please guide me on how to fix this.

Comienza con la implementación detrás de ns doctor y su comprobación de la variable de entorno del Android SDK; el issue no especifica ningún archivo ni prueba. Verifica el comportamiento con ANDROID_SDK_ROOT establecido y ANDROID_HOME ausente, y confirma que ns doctor reconoce el SDK sin la advertencia.
