Missing code content in Tutorials

[nohit]

Many of the tutorials have empty example code boxes.

Examples:

https://docs.juce.com/master/tutorial_look_and_feel_customisation.html

https://docs.juce.com/master/tutorial_sine_synth.html

https://docs.juce.com/master/tutorial_slider_values.html

(I coud not add more images as it’s not allowed for new users)
