Lesson 23, stacks example, array items doesn't match gems.

Issue description:

Lesson 23, stacks example, array items doesn't match gems in the left panel.

To Reproduce Steps to reproduce the bug:

1. Go to https://gdquest.github.io/learn-gdscript/staging/#course/lesson-23-append-to-arrays/lesson.tres
2. Scroll down to the heading: Using arrays as stacks
3. See the first interactive example.

Observed behavior

The left panel shows the following gems, from top to bottom:

• blue gem
• yellow gem
• fire gem

But the code in the right panel uses the same name for all three items in the array:

var crates = ["fire gem", "fire gem", "fire gem"]

Expected behavior

The code should probably match the gems in the left panel.

var crates = ["fire gem", "yellow gem", "blue gem"]

The gems in the left panel seem to change. A green heart gem appeared at the top this time:
