Fix bug with scrolling inside the container on android

The bug

The mini app is minimizing, when user creates these actions: reversible scrolling, scrolling inside containers, and swiping elements down. The bug is not permenent: it happens often but not always. Additional details here

Reproduce

1. Open android tg app
2. Open this tg bot
3. Open web app with menu button and expand it
4. Scroll down
5. Scroll up (here it is. Web view is closing)

Here is how code of this app look like: https://stackblitz.com/edit/typescript-gufuwl?file=index.ts

Importance

This problem prevents users with Android devices from working with Mini Apps. Developers are unable to create applications with the full range of advantages of web applications: reversible scrolling, scrolling inside containers, and swiping elements down. Therefore, I propose a solution to avoid all of these issues.

TLDR of the commit:

• ignore swiping the container with web app when it's expanded
• add menu's button "Minimize" to minimize web app

In additional, I can suggest adding swipe only when user touches the part of container which is higher than webview (when its expanded). The place where the name of webApp is written
