e2e: `KeyboardAvoidingView` tests

[kirillzyusko]

📜 Description

Added tests for KeyboardAvoidingView component.

💡 Motivation and Context

To assure better quality of the library we need to perform automated checks. KeyboardAvoidingView had 0 e2e tests so I decided to improve the situation here.

The problem is that on Android after switching behavior/package properties the Detox struggles to press button again. I think I'll fix it later, now I want to have a solid base for future tests.

📝 Checklist
