style: 💄 vtex setup

[emersonlaurentino]

What is the purpose of this pull request?

I added the standard vtex settings that we use for all projects.

This includes eslint and prettier.

I removed the husky and lint-staged part because there are many problems and I would not be able to raise this PR. However, I will open an issue to be added later. (#1081)

What problem is this solving?

code linter and formatter

How should this be manually tested?

run yarn lint locally and see all eslint errors
