[EXTERNAL] fix: clarify set-internal-vars expected output, remove misleading commas

[e-aub]

Why?

The expected output in the exercise documentation was misleading: it showed the array elements with commas one, two, three, four, five while the actual test expects them to be space-separated one two three four five. This change clarifies the expected output to prevent confusion when implementing the script.

Solution Overview

Updated the instructions and expected output for set-internal-vars.sh to remove commas between array elements. The script now clearly indicates that the array should be printed as space-separated values, matching the automated test expectations.

Implementation Details

• Removed commas from the example output in the exercise description.
