Adds a stamp sound effect when stamping papers (#72367)

## About The Pull Request

This pull request adds a .ogg file of a stamp stamping a paper, a
playsound function for stamping a paper, stamping a paper while blind,
and stamping yourself in the head to commit suicide.

In addition, it modifies the attributions.txt file to include credits to
the creator of the stamp noise.

## Why It's Good For The Game

Most item interactions tend to have a sound effect that plays. Putting
most items down, throwing them, cutting certain items with the knife,
scanning bounty cubes, putting a destination tag on a package, etc. all
play sounds, which makes it a bit odd that stamping papers doesn't. This
PR adds audio feedback to stamping papers.

## Changelog

Stamping paper now makes noise.

:cl:
soundadd: Added a new sound for stamping papers with a stamp. On an
unrelated note, there are reports of stamp-based suicides becoming more
noisy.
