Removing format package

[evertonfraga]

Given that now we're using Prettier as a plugin of ESLint in our lint package, I believe we should retire the @ethereumjs/config-format package, which sole objective was to run Prettier in check and fix modes.

We haven't changed much in the format package lately, so I had never fully wrapped my head around it. Once I did, 💣💥.

sounds good 👍 can eslint run prettier fix then? that’s great

[evertonfraga]

Yes!

if you run eslint with the --fix flag, your code will be formatted according to prettier style.
