I'm a beginner participating in Hacktoberfest 2024 and came across your project. I’ve added a link to the Hindi version of the Prompt Engineering course in courses section under subtopic artificial intelligence  to make it more accessible for Hindi-speaking users.

* Updated title of course as per resource

I have updated the title of the course as per resource as instructed so please do consider and merge it as soon as possible
