Add automatic code formatting to pre-commit

[Vayel]

User story

Code formatting for front-end is to be done manually, which is a bit painful. Instead, it should be done automatically.

Best solution for this problem

Run prettier during the pre-commit hook.

@Betree what does src mean here? I can't see any src directory.

Should I just run the hook on app/**/*.{js,jsx}?

That sounds like a misconfiguration from https://github.com/CaptainFact/captain-fact-frontend/pull/224

app/**/*.{js,jsx} is fine, we can also add cypress/**/*.{js,jsx} too but that's not a requirement.
