[Very Minor Correction] Period goes on next line on Lesson 4 - Drawing a Rectangle

[ErnestoCampese]

Issue description: A very simple correction I guess, and not urgent at all, but I will do it anyway in the hope to help you make it perfect. On lesson 4 ther eis a sentence that says: We present you the turtle... well in that line the period goes on a new line. Maybe the sentence could be shortned a bit to give space to the period. I know, very OSD report 😆
