Testing key value in http_request_class is empty so it seems that is not working correctly

**Your Godot version:** 4.2

**URL to the documentation page:** [networking/http_request_class](https://docs.godotengine.org/en/stable/tutorials/networking/http_request_class.html#scripting-the-request)

**Section:** Scripting the request

**Issue description:** I was following the tutorial and thought something was wrong. When you receive the request and access the key "name", its value is empty, so nothing is printed. It appears that the name value in https://api.github.com/repos/godotengine/godot/releases/latest is currently empty. I would make a PR but I'm not familiar with what the GitHub API usually returns
