Implement Search Functionality for Courses, Projects and Blogs

[kunal2812]

Implement search functionality on Courses, Projects and Blog pages. Users should be able to search for courses, projects and blog posts based on their headings, making it easier to find relevant content quickly.
Only those Courses, Projects and Blogs should then appear on the page that matches the search string in the search box (Can use AJAX)
This will allow content to be filtered and displayed in real-time based on the user's search string.

Note:

• Create a new branch for every task to isolate changes
• Start working on the issue only when it is assigned to you
• Submit the PR on time, no extra time will be allotted
• Follow the existing theme of website
• Don't request for the issue if it has locked label on it (will be unlocked after dependencies are fixed)
