Fix: 3741 - enable fetch-examples script to resolve both ts and js files

[clairep94]

Fix #3714

• script/fetch-examples calls script/examples
• inside script/examples we import the newly migrated /server/models/user file
• this file needs to know to try to resolve both ts and js files, instead of just js
