Documentation references pressing `Alt + Space` on macOS, but there is no `Alt` button on Macs

[valentinegb]

Godot Version

v4.1.1.stable.official [bd6af8e0e]

Issue Description

In the Godot documentation on that page titled "First look at Godot's editor" and under the section titled "Integrated class reference", it mentions that you can open the class reference by pressing Alt + Space on macOS. This cannot possibly be true, because Macs do not have an Alt button.
