Header name should be properly capitalized (Content-Type)

"Content-type": "application/json"

Hi, thank you for your website and code!

I am following along with "axios": "^1.1.3". I just spent a painful 2 hours fighting a bug where the Axios service would always POST with an empty body. Thanks to Postman, I realized the header was not being read. It turns out it needs to be properly capitalized:

"Content-Type": "application/json"

And this fixed my issue.
