Ruby runner: uninitialized constant DataStoreFactory

[pimar57]

Hi,
I think in https://docs.gauge.org/writing-specifications.html?language=ruby#data-store
examples should have "Gauge::" before each "DataStoreFactory...." (which raise a 'uninitialized constant DataStoreFactory' error) to become "Gauge::DataStoreFactory...." which works fine in ruby runner.
Nice work guys!
