Add an HTTP request cheat sheet

[jvns]

I'm a big fan of using curl to make HTTP requests, but I'm always forgetting how to do basic things in curl, like "how do I make a POST request with JSON again?". So I was thinking it could be useful if curl had an official cheat sheet. I know there's a tutorial, but it's quite long and personally I only use an extremely minimal subset of curl's functionality.

This is a pretty rough draft but I wanted to see if there's interest before getting into the details. I linked each option to the appropriate place in the man page.

Here's what it looks like visually right now.

some todos:

• not sure about the name yet (maybe it should be http-cheat-sheet.html?). I feel like it's useful to have a cheat sheet just for doing HTTP(S) requests in curl even though curl does much more.
• Probably the CSS should be simplified or look a little closer to the curl website's aesthetic
• The CSS uses nested selectors, that needs to be fixed because not all browsers support nested selectors yet
• Maybe mention how to set cookies?

There is an official curl cheat sheet at https://curl.github.io/curl-cheat-sheet/http-sheet.html There is also curl/curl#18151 to add it to the command-line tool as well.

I am always in favor of improved documentation - and I like the proposed look. This could be a way to bring a good-looking http cheat sheet to the curl website.
