Summary:
Since Prettier 2.0, the default for the `arrowParens` option has changed from `avoid` to `always`.
In preparation for upgrading Prettier in Xplat to 2.1, add `arrowParens: 'avoid'` explicitly to configurations that were missing it so that we do not have a change of behaviour when upgrading.

Summary:
This fixes an issue where the Prettier config was set to the `fb` (Facebook) values for all users of the `react-native-community/eslint-config` package. This was due to [this line](8f186b84ae/packages/eslint-config-react-native-community/index.js (L219)) in the config file.
It was causing issues like these:
* Errors when using newer versions of `eslint-plugin-prettier` (you had to use a version that was >1 year old): https://github.com/facebook/react-native/issues/24564
* Errors due to the Prettier parser being forced to be `flow` when using Typescript: https://github.com/typescript-eslint/typescript-eslint/issues/481
This PR:
* Changes that line to remove the explicit `fb` config so users can set their own.
* Moves the React Native Prettier config to `.prettierrc` so ESLint, Prettier, and code editors can all read from the same place.
* Upgrades both `prettier` and the `eslint-plugin-prettier` to the latest versions.
[General] [Fixed] - Stopped the Prettier config being set for all users of react-native-community/eslint-config
