Clean Code: sumArray section missing example code about curriculum HOT 4 CLOSED

Thanks for raising this @txfgh.
This is an oversight from when the original array-based example was changed to a string concatenation example in #27361, but the text following it wasn't amended accordingly.

Opening this up for assignment if someone wishes to comment below.
The verbiage in the two paragraphs in question need to be amended so that:

• the variable/function names match the current string concatenation example
• the "what is an array" sentence is omitted since we no longer have an array example
• the second paragraph does not reference a q variable, as the current example does not have one.

I wouldn’t mind working on it if it's OK @MaoShizhong

I just realised something the PR I made is for my forked curriculum repository, is there a way to fix this or do I need to open another PR? @MaoShizhong

I managed to resolve this 😅 and learnt quite a bit from this. Please consider the PR below.
