Set up linters with Pre-Commit Hooks

[matthewcn56]

As is, we can commit and make PRs before checking if our pages properly fit to our codebase's formatting standards. If we can make a github action to run yarn lint-fix and check to make sure that no errors occur on commit, we can prevent scenarios where we open PRs that won't build on netlify due to CI errors.

This can be achieved through husky precommit hooks that's similar to what's used in teach-la's typescript react starter!
