Godot version:
Master 2a0de6d

OS/device including version:
Windows 10

Issue description:
Calling a coroutine in _ready() using await fails with error Trying to call an async function without "await".

Example script:

extends Node

func _ready():
	await get_tree().create_timer(1.0).timeout # works
	await _async_func_test() # fails

func _async_func_test():
	await get_tree().create_timer(1.0).timeout

Steps to reproduce:

1. Add the script above to a node
2. Start game
3. Observe debugger break and error

Minimal reproduction project:
script-await-ready.zip

Fixed in #43890, closing.

I thought it was fixed, but I can actually still reproduce it in 68117f5.

same error,sample code:

extends Button

func _ready():
	await wait_confirmation()

func wait_confirmation() -> void:
	print("Prompting user")
	await self.button_up # Waits for the button_up signal from Button node.
	print("User confirmed")

Run the code will give this error: Trying to call an async function without "await".
