Add Let's Connect button functionality to redirect to Linkedin profile

[992manav]

Fixes #302

I have fixed the issue with the "Let's Connect" button on the contributor's card. The button now successfully redirects users to the contributor's LinkedIn profile when clicked. This ensures that users can easily connect with the contributor via LinkedIn.

Ensured the link opens in a new tab for better user experience. This fix aligns with the expected behavior and enhances the usability of the contributor's card.
