[BREAKING CHANGE] Prettier support as default

[koba04]

Currently, we support Prettier with additional presets, but we mostly use Prettier in our projects, so I'm considering supporting Prettier in all presets. It means all presets we provide support Prettier and we can remove prettier presets.

If you don't use Prettier, you can still use our presets because our Prettier support is just removing stylish rules conflicting with Prettier. If you want to care about code format, I recommend using Prettier instead.
