Add -I parameter to curl command

[gijswijs]

When checking the rate limit while using your app's client ID and secret, you need to supply the -I argument to show the header of the response, containing x-ratelimit-limit and x-ratelimit-remaining

Why:

Closes #16527

What's being changed:

Missing argument -I is added to the curl command: curl -u my_client_id:my_client_secret -I https://api.github.com/user/repos

Since the documented request output shows only the API response header, this is a valid improvement. Looks great! 🎉
