doc: spice-example-sh: fix ticket/csrf extraction

We extract them from the json data by first deleting all
quotes, then deleting everything up to their entries, then
everything after the next comma. If the entry is at the end
there's no comma, instead there are closing braces, so we
need to strip away these as well.
