Well spotted.
SVN = "Apache Subversion" is a software to help with software development.
Another popular option with the same goal is "git".
Basically tools that help to keep track of edits, work together with others or just publish program code.
See this thread for an example: https://www.lfs.net/forum/thread/107981-Telemetry

Different websites exist with the software already set-up and you can simply register an account. (Like creating an account at google-mail instead of running your own email-server.)

Lately sometimes people misuse these websites for file-sharing.
It is not meant for that and of course ripped files violate the terms of usage.
So when someone on sketchfab writes that he "found it on the svn" (or git/github) it means he downloaded it from such a place.
