Information about licenses

I have searched the website after information about licenses for using, redistributing etc. content and software is possible. Unfortunately I have not found anything. Right now I would like to use the following picture: https://gitlab.torproject.org/tpo/anti-censorship/pluggable-transports/snowflake/-/wikis/uploads/8716c3ba1226bd90009268a777ed2ccb/snowflake-diagram.png in an wiki article about snowflake. Is it allowed, which credentials need to be fullfilled. In generell it would be very helpful, if the top landing site: https://gitlab.torproject.org/tpo/team where you are redirected from https://gitlab.torproject.org/, would contain a section with all needed license information about Tor.
