Increase the maximum height of notifications by 20%

This value is the exact height of 4 collapsed notifications + padding (88*4+2*3)

We are increasing the height of notifications because we've increased the font sizes, line caps, and paddings, reducing the amount of content that can be shown in the same area.  Specifically:
* BigPictureStyle's pictures were getting quite cramped, showing at almost 3:1 aspect ratio in some cases
* ConversationLayout for group chats have larger icons and paddings that reduced the number of messages visible to 2, but this change restores that to 3.
