Add Newsletter Subscription Feature to Stark Tech Portfolio

[priyachau12]

Feature Description:
I would like to add a Newsletter Subscription feature to the Stark Tech Portfolio website. This feature will allow users to subscribe to regular updates, keeping them informed about the latest news, product updates, blog posts, and more. The newsletter will drive engagement, build a community around our content, and foster a loyal user base.

Key Features:
Easy Subscription: Users can easily subscribe to the newsletter directly from the navbar for seamless access.
Regular Updates: Subscribers receive periodic emails with curated content, updates, and tips to keep them engaged.
Targeted Content: Newsletters will include insights, feature highlights, tutorials, and other valuable content tailored to user interests.
Unsubscribe Option: Users can unsubscribe at any time, ensuring flexibility and user control.
Adding a newsletter subscription option will enhance user engagement and provide a consistent communication channel, helping to build a strong connection with our audience.

Please label this issue as enhancement, level2, and gssoc-ext. Thank you!
