[MIRROR] Brings back Bartenders fountain pen [MDB IGNORE] (#19673)

* Brings back Bartenders fountain pen (#73775)

## About The Pull Request

When PDAs were switched over to tablets, it seems that the bartender's
fountain pen was forgotten. This PR will add it back as the round start
pen of choice for bartenders, replacing the old generic one.

Bardic bartenders rejoice.

## Why It's Good For The Game

A lot of bartenders are snobby and would use fountain pens. Non-snobby
bartenders would still be able to write vulgar words with precise
calligraphy abilities. Both sides win.
