CI Github Action Improvement

[karkir0003]

Context

In #83 , I attempted to create a GitHub action to automate the npm run lint and npm run prettier checks. However, after #83 got merged, I realized that there is a better setup that can simplify the problem. This PR tries to make things right

Changes Made

• Updated the ci.yaml to act as a validation layer for enforcing the formatting standards as outlined in the contribution guidelines
• Updated CONTRIBUTING.md to bring awareness to the automated hook to auto apply prettier and linting formatting standards
• Created a .husky pre-commit hook that on commit automatically lints the staged files! No need to remember to manually run npm run lint and npm run prettier

Test Plan

• Dry run of the CI Action here
  1. Created a new branch off of this one with the improved action
  2. Ran npm run lint && npm run prettier
  3. git push
  4. Create PR as seen above and the CI run succeeds
