This is a mistake. I added veriT in the development version but it led to some errors, and so it was taken out of Isabelle before the release. I simply forgot to update the documentation.
Right now there's not much you can do with veriT. There has been some interesting work, by colleagues of mine (in CC:), notably on a tighter integration of veriT in the "smt" proof method. See
Unfortunately we haven't yet build an Isabelle component based on the modern version of veriT. This requires compiling binaries on three platforms, which is a bit tedious, and I've lost my Windows installation in an upgrade... My goal for 2020 is to get the binaries back on track and update most of the Sledgehammer components (and include new ones, e.g. Leo-III).
