plugin_repositories_batch - Unexpected input(s)

[txmxthy]

Hi. I was going back through my metrics after setting it up 3 years ago and found that this "plugin_repositories_batch" parameter is now just "repositories_batch", I changed it in the YML and it seems to have got rid of the warning that was being created every time the metrics ran.

Its been a long time since I set it up and I don't fully understand the generator works, but searching github found quite a few repos (at least 122) with the same config which have the same error across hundreds or thousands of runs each.

I thought it was worth reporting (though if its entirely on the user config I guess there is not much you can do!)
