Fix a prettier config (#33)

### What has been done

- Remove
[unnecessary](#16 (comment))
configuration for prettier
- Remove properties from `package.json` - The prettier is config in the
`dapp/.prettierrc.js` file. This configuration depends on the
[type](https://stackoverflow.com/questions/71184604/prettier-fails-when-declaring-type-module-in-package-json)
value in your `package.json`. Adding "type": "module" in `package.json`
makes all `.js` files ES modules, and then they can only be imported in
other ES modules. Prettier is not able to import `.prettierrc.js`
because it is now an ES module. So let's remove that property.
