Revert to @babel/eslint-parser in eslint-config

Summary:
Motivated by facebook/hermes#1549. This was originally changed in facebook#46696, as our internal Flow support had diverged from `babel/eslint-parser` (facebook#46601).

We effectively have three flavours of JavaScript in support:
- Flow@latest for the `react-native` package, shipped as source — uses `hermes-parser`.
- TypeScript for product code (community template, Expo) — uses `babel/plugin-syntax-typescript`.
- Plain JavaScript or Flow in product code, *which may be extended with additional user Babel plugins and needs lenient parsing* — uses `babel/plugin-syntax-flow` via `babel/eslint-parser` (**this change**).

I'd love to simplify this 😅.

Switching to `hermes-eslint` for the RN monorepo codebase (D63541483) is unchanged.
