Verification steps

Tooltip component should look like the design. I believe the only example right now is on the ? on the create site screen.

@shrouxm do we want to use this as an opportunity to get rid of NativeBase in tooltips?

[shrouxm]

react-native-paper doesn't offer a tooltip component which is able to match the spec, so it would increase the effort required to find and vet another library and/or implement it ourselves. this doesn't further entrench us in nativebase and it at least gets us compliant with the spec, so i don't see any reason to couple that work together.

My only comment would have been to get us off of NativeBase if possible, but maybe that just isn't a practical goal right now.
