Module 3D: Label Imaging - Add Working Resource for Forceps to T4

[debpaul]

See https://github.com/EntCollNet/BugFlow/blob/master/modules/module_3/module_3D.md

URL to SPNHC document in Resources for T4 doesn't return the expected PDF.

• [x] sent message to SPNHC to ask to see if it still exists somewhere
• [x] looked up this paper at iDigBio by Rod Eastwood, titled - Efficient removal of insect specimen pin labels with modified forceps
• [x] need to add the above to the Resources for T4.
