website: export V23_GOPATH
The shell scripts for setting up the tutorial environment runs the
shell snippet from setup.md twice (`mdrip --preambled 0`): once inside
the callee shell and one in a restricted inner shell. If the
V23_GOPATH does not exists then the second run fails. This fixes the
issue by exporting the V23_GOPATH.
