(MODULES-11371) Add Vox Beaker gem

In 057188e, we updated the module according to PDK template 7.2.1,
which updated puppetlabs_spec_helper. The updated version of
puppetlabs_spec_helper removed the Beaker rake task, which we use
for acceptance testing.

This commit adds the voxpupuli-acceptance gem, which re-adds the
Beaker rake task.
