adb instead of scrcpy for easy install

[whyvn]

curious why the suggested method is to install an apk using scrcpy drag and drop instead of a simple adb install app.apk? adb is already assumed to be installed because its mentioned already in the guide, and scrcpy adds an extra layer of complexity for no reason which can lead to a more confusing experience like if you get a fake context error and are unable to use it
