Old API endpoints missing in documentation

[sandevins]

Some time ago, I checked the documentation and the API and FAUCET endpoints were specified in some page of it. Now it seems to be missing. The endpoints I am using are the following.

const API_ENDPOINT: &str = "https://api.testnet.iotaledger.net/";
const FAUCET_ENDPOINT: &str = "https://faucet.testnet.iotaledger.net/api/enqueue";

They still work, but I was also curious if there was a way to test them (like a GET request to see if the endpoint is correct).
