Typographical error in day3 task 1

[Hamdi-Limam]

For the day3 task1, I think you wanted to say convert it back to "dictionary" instead of JSON.

The issue: "Task 1: Convert a dictionary object to JSON and then convert it back to JSON. Do the same with XML."

Fix: "Task 1: Convert a dictionary object to JSON and then convert it back to dictionary. Do the same with XML."

I figured out that there is another issue in the same file.

Issue: the first online problem is called "Validate Roman Numerals" but it points to a HackerRank loops problem.

Fix: change the link to "HackerRank Validate Roman Numerals problem".

I can commit again this PR if you confirm for me the issue.
