Localize the : with string createProject.fileSelected

[imnasnainaec]

Test by making sure the three updated components look right when a file is selected. Test in all 6 of our interface languages.

• In French, there should be a space before and after the colon ( : ).
• In Arabic, the rtl order within the interface should be: تم تحديد الملف on the right, then the colon (:) in the middle, then a space, then the filename on the left.
