[Organization] Cleaning up folders and standardizing tutorials

[harshpavuluri]

Summary: With the Tutorials section of Ironhacks becoming standardized, I'm not sure if keeping the same structure of folders is necessary. Most of the files are just copies of the others with some modifications. I think this can be cut down and just have a list of files that are accessible. This will reduce the amount of copies that we have and maintain versioning through the pull requests and git commits. This way we can revert any changes without linearly expanding the amount of data that we are using in this repository.

*Also this makes it easy to copy and paste the markdowns and make sure that the links are pointing to the right areas

Tasks:

• [x] Put files Spring 2022 into the top level
• [x] Remove all other folders
