LP2051038 Printing Holds Grid prints hold status number instead of text

The display text for the Hold Status column is locally derived for each
Hold Status number in the template, but the typescript file only sees
the number so that's what it prints/downloads.

This adds the same wording that is in the template to the CellTextGenerator
so that the download / print will match. (Note that LP2051037 suggests
moving the wording into a table so that this type of redundancy could be
resolved.)

Release-note: Holds grid can now print / download the Hold Status column.
