Readme should be updated: adb command

[sayemPasha]

Readme states that-
2. Execute below command to push models to Android device respectively (must be physical device) adb push /the/path/to/gemma-2b-it-gpu-int8.bin data/local/tmp/llm/
but the downloaded model is 'gemma-1.1-2b-it-gpu-int4.bin'
which causes the adb push command not working
Solution: Update the adb command
adb push gemma-1.1-2b-it-gpu-int4.bin data/local/tmp/llm/
