🪲 Fix bug in custom Skulpt module extensions

[boryanagoncharenko]

This PR addresses the following issues:

• When the body of an if-pressed command contains more than one turtle functions, only the first one will be executed.
• When the body of an if-pressed command contains time.sleep(), the execution would terminate when reaching this line.

Fixes #5729 #5681

How to test
Run locally, go to level 15 and run the following scenarios:

1. Check that the code below outputs all items in the list. Note that they should not appear at once, but with a tiny delay in between:

lijstje is "1", "2", "3", "4", "5"
if x is pressed
    for dier in lijstje
        print dier
else
    print 'onbekend dier'

2. Check that when pressing x, all statements are executed. Note that the waiting-for-key-press modal should appear and then disappear while the action is being executed. Note that pressing the x button while the turtle is moving should not trigger a new run. If an error occurs, the keys should not be animated anymore.

i = 0
while i < 20
    if x is pressed
        turn 10
        color 'blue'
        turn 90
        forward 50
        color 'red'
        turn 90
        forward 50
        color 'orange'
        turn 90
        forward 50
        color 'green'
        turn 90
        forward 50
    else
        turn -15
        color 'blue'
        turn -90
        forward 50
        color 'red'
        turn -90
        forward 50
        color 'orange'
        turn -90
        forward 50
        color 'green'
        turn -90
        forward 50
    i = i + 1

Ahh it makes sense! AsyncToPromise is the one to use
