Adds message for previous winners of trade within 5 years

[TheDancingClown]

📝 A short description of the changes

• There should be an additional message for previous winners of International Trade if they have won within the last 5 years. This builds upon the previously used data-year-value to add further checks and add a message if the year selected is within 5 years of the current year.
