That seems to be correct. https://git.apache.org/poi.git and the github mirror at https://github.com/apache/poi don't link to https://svn.apache.org/repos/asf/poi/poi-site.
For now, Subversion is your best bet. I think there was some discussion about moving the project to git, rather than having a read-only git mirror.
