Outdated method name for ResourceLoader (load->LoadFromFile)

[MagmaGuy]

Your Godot version: 4.2

Issue description: Outdated method

URL to the documentation page: https://docs.godotengine.org/en/latest/classes/class_resourceloader.html and https://docs.godotengine.org/en/latest/classes/class_image.html#class-image-method-load

The method load seems to have been replaced with the more explicit load_from_file (LoadFromFile in c#)
