[native] Prevent CoolOrNerdModeSelection emojis from rendering with opacity on Android
I noticed that the emojis in the CoolOrNerdModeSelection screen were kind of blurry. I did some Googling and found this solution.
On iOS, setting the text color of emojis has no effect. On Android, setting the text color of emojis to black seems to make them render with full opacity.
Depends on D8002
Also tested on iOS to confirm no changes. Note that the registration flow only supports dark mode, but it appears that color: 'black' has the same impact on Android in either mode.
