[developer experience] Add git hook for linting code

[benfurber]

Regularly the ci steps of PRs fails simply because of linting issues that would be easily fixed by running yarn format. This wouldn't happen if a git hook ran this command for commits. https://git-scm.com/book/en/v2/Customizing-Git-Git-Hooks

[mariojsnunes]

is this happening because prettier/eslint isn't correctly configured?
