Issue description

Not really a bug, but rather a feature that was only partially implemented. This is a reminder for me (or anyone else) to implement it: #35666 (comment)

The feature in question was backported to 3.x, so this should also be done in both master in 3.x.

Steps to reproduce

• Create an action named move_forward (without a "s").
• Add the following code to a script.

func _physics_process(delta):
	# It's `move_forwards` with a "s", this time.
	# You need to have a typo that's close enough to the intended string for the suggestion to be printed
	# once this feature is implemented.
	if Input.is_action_pressed("move_forwards"):
		pass

• Watch the error spam in the console, but notice it doesn't make any suggestions because we are using the Input singleton instead of an InputEvent.
