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](https://www.figma.com/file/dTWHwMDdZ8RUrR3rFmzxey/Oppia-deprecation-project?type=design&node-id=0-1&t=oJZSjk9XX4yQKo4f-0).
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
