Resolves #9175
When saving a PDF, there is a comment that mentions what Pillow version is being used.
Pillow/src/PIL/PdfImagePlugin.py
Line 224 in 97a4d1f
This PR removes the version from the string. I don't think it's necessary, and may conceivably help an attacker - if software using Pillow generates PDFs, then an attacker could determine what Pillow version is being used, and they might learn that it is an outdated version with known vulnerabilities.
