InputEventMIDI is incorrectly written InputEventMidi (upper case MIDI instead of Midi)

[Phibonacci]

Your Godot version:
4.2.1

Issue description:
The InputEventMIDI type in the doc is actually called InputEventMidi. This is a minor mistake and IDE will easily spot it but the example code is invalid for this reason.

URL to the documentation page:

https://docs.godotengine.org/fr/4.x/classes/class_inputeventmidi.html

I'll open a pull request myself later eventually if I find the time.

Where is it called that? Do you mean in C#, that's wrong indeed

I'll go through and fix some cases across the codebase :)

Yes, I should have mentioned this. I used C# exclusively.
