Ditch eslint-plugin-prettier and use eslint-config-prettier (#3910)

- We don't need `eslint-plugin-prettier` since we now use Prettier as a formatter. Moreover, it conflicts with the specified rules because it doesn't consider our Prettier configuration.
- Use `eslint-config-prettier` to turn off all unnecessary rules that might conflict with Prettier.
