What are the steps to reproduce?

What happens?

What do you expect to happen?

Please tell us about your environment:

• [x] Node-RED version: 3.1.9
• [x] node.js version: 20.13.1
• [x] npm version: 10.5.2
• [x] Platform/OS: Windows
• [x] Browser: Chrome

In anticipation of the coming switch to Onecall 3.0 I registered for a subscription. However, it was not clear to me how to invoke a call to 3.0 in the openweathermap node. After some digging through the code I found that the option onecall 3.0 can be found in the dropdown menu of the node properties page as "combined current weather/forecast for". To help users, I prepared a PR for the help file.
