Style Change: New styles for the Oppia Deprecation Dialog Design

[kkmurerwa]

Explanation

The introduction of the new deprecation dialogs for the App/OS Deprecation feature led to a minor redesign of the dialogs. This includes style changes to the dialogs that will display various deprecation messages. The proposed dialogs can be seen on this Figma link. When merged, this PR will introduce the new theme needed to achieve the desired dialog designs.

The difference between the current and the proposed dialog are highlighted below
