Description

Instructions for Reviewers

I added a function for year input to convert partial number years to full year values.

List of changes in this PR:

• Create the function called "completeDate" form component https://github.com/VictorHugoDuranS/dspace-angular/blob/4a2a911c795671cd72ad2dc96990a6f7b3ab64c3/src/app/shared/form/builder/ds-dynamic-form-ui/models/date-picker/date-picker.component.ts
• Validate if the year size is 1, then I set the default value as the current year after that 00 and finally the typed value, I consider the user typed that value as initial years.
• Another validation is for lengths between 2 and 3, this value is overwritten in the current year considering the positions from left to right.
  *Finally if the value has length of 4 return the value written
