Fixed semantical error in diagram in section 6.3

[FlashEb]

• I changed the second diagram in section 6.3 to be more accurate with its description.
• I got the new diagram from ChatGPT, this is the link: https://chatgpt.com/s/m_6824d51fcb4081918fc38840a209cf19
• The image was slightly edited by me to add a quotation to the other side of the "anotherFile" in the diagram.
• This Fixes issue #231.
• It has been tested by checking for the change in the Pretext textbook through my local host.
