[Feat]: Add github link in navbar

[Akanksha-202]

Is your feature request related to a problem? Please describe.

Users visiting the website may want to contribute their Python scripts to the repository, but there is no direct link or easy access to the GitHub repository from the website.

Describe the solution you'd like.

Add a GitHub link to the navbar, allowing visitors to easily access the repository and contribute their Python scripts if they wish.

Describe alternatives you've considered.

1. Adding a "Contribute" button on the homepage that leads directly to the GitHub repository. 2. Creating a "Share Your Script" section on the website with a call-to-action button to contribute to the GitHub repository.

Show us the magic with screenshots
