[just before launch] Update Godot to the latest stable version

[pfertyk]

After we have enough exercises to launch the track, let's update Godot Engine to whichever stable version is available at that point.

This is more related to our test runner repo, but I'm creating the issue here, since it might require some changes in exercises.

Definitely. For example, resistor-color-expert is broken on the latest:

Checking resistor-color-expert exercise...
resistor-color-expert: testing...
Godot Engine v4.4.1.stable.official.49a5bc7b6 - https://godotengine.org

-> test_orange_orange_black_and_red
-> test_blue_grey_brown_and_violet
-> test_red_black_red_and_green
-> test_green_brown_orange_and_grey
-> test_one_black_band
-> test_orange_orange_yellow_black_and_brown
-> test_red_green_yellow_yellow_and_brown
-> test_blue_grey_white_red_and_brown
-> test_violet_orange_red_and_grey
-> test_brown_red_orange_green_and_blue

If I swap in Godot Engine v4.2.2.stable.official.15073afe3, these pass just fine.
