[Style] Add GitHub action for linter and pre-commit hook formater

[Neet-Nestor]

Overview

Currently this repo doesn't have a formatter setup. Besides, even though we have ESLint rule set up, these rules are not currently enforced in this repo.

This PR adds the following to ensure better code quality:

• Add prettier for code auto formatting
• Run prettier format on every commit using pre-commit hook using husky
• Add GitHub actions for automatically checks ESLint and Prettier on PRs and pushes

All other changes are just auto formatting and can be safely ignored.
