bug: Render issue in Contribute Cupertino Modal Bottom Sheet

[abhay1821]

What

• The Contribute Cupertino modal bottom sheet UI breaks on devices with screen height less than 847 pixels.

Steps to reproduce the behavior

1. Go to the Profile tab
2. Click on Contribute list tile
3. Click on device preview
4. Change the model with any resolution with height in pixels lesser than 847 pixels.
5. See the UI breaks to render.

Expected behavior

The UI of the model bottom sheet should not break on devices with smaller dimensions.

Why

• This is important for users to have a complete view of the components in the release build elsewhere in the release build the UI won't get rendered and be visible to the users.
• This type of render issue also hits the app performance badly.

Part of

• Add the issue number preceded by UI/UX fine tuning (tracker) #1171
