Remove explicit folly version

[okwasniewski]

Hey!

Based on other fabric compatible libraries removing explicit folly version, I wanted to also remove it here.

Based on:

• https://github.com/software-mansion/react-native-screens/pull/1549
• https://github.com/th3rdwave/react-native-safe-area-context/commit/eb111ff4eebc8d06ca01e7d12d9661147d03da20
