I added Arabic translation of all DAN probes which were quality checked by human to ensure suitability to the Arabic language, added Arabic detector for the probe. The new probes and detectors passed the test during development.

It also seems that the code here includes donotanswer ala #1017 -- is that intended?

@erickgalinkin, I think the bcp47 selection can be deferred. For now for non en probes should not be marked active by default and the detectors will only be selected explicitly be a probe or override. This puts the onus on the user to force selection of this items via configuration options when preforming a run.

Also all comments I made in review or #1017 will apply here as well. For now we can have the separate languages as unique classes that can be selected explicitly and in future iterations we can consolidate those classes into language specific instances of one class.
