[Export ETA Date format] Exporting ETA column should be in usable Date format

Currently, when exporting feedback, the ETA column has the date value in milliseconds.

It would be more convenient to have it in more commonly used date format as other columns being exported.

That way there isn’t the need to use extra conversions to get the date from the value:

=(A1/ 86400000) + DATE(1970,1,1)
