{GSSoc'23} Sitemap Addition for Website

**Is your feature request related to a problem? Please describe.**
Yes, the feature request is related to a problem. The current problem is that the website does not have a sitemap. Without a sitemap, search engines and users may struggle to navigate and discover all the pages and content on the site. This can lead to lower search engine rankings, reduced visibility, and a poor user experience.

**Describe the solution you'd like**
The solution I would like is to have a sitemap added to the website. The sitemap should be a file that lists all the URLs and metadata of the website's pages. It should be automatically generated and updated dynamically whenever new content is added or existing content is modified. The sitemap should follow the XML sitemap protocol, which is the standard format recognized by most search engines.

**Describe alternatives you've considered**
