chore: add prettier auto-formatting github action

[Rohit3523]

Proposed changes

I have implemented a new GitHub Actions workflow to automatically format our codebase using Prettier. This workflow runs automatically on every commit and pull request, with the exception of direct pushes to the develop branch.

The workflow utilizes Node.js 22 (as per the current LTS schedule: https://nodejs.org/en/about/previous-releases#release-schedule) and npm ci for dependable dependency installation. When triggered, it runs the Prettier formatter across the codebase, and if any formatting changes are detected, it automatically commits and pushes these changes with a standardized commit message: "chore: format code with Prettier".

This automation eliminates manual formatting tasks, reduces style-related discussions during code reviews, and maintains a consistent code style throughout our codebase. The workflow has been thoroughly tested across various scenarios including push events to feature branches and pull request events, confirming both its functionality and proper branch exclusion rules.
