Wrong configuration line in docs (forward-zones vs. forward_zones)

[wopfel]

Hi,

forward-zones should be written as forward_zones (underscore) in the docs for the yaml file.
Starting the service using forward-zones in the yaml file results in an error.

I've spotted the misspelled lines here: https://docs.powerdns.com/recursor/yamlsettings.html#recursor-forward-zones

And maybe this is the related source:

pdns/pdns/recursordist/settings/table.py

Lines 1076 to 1078 in 3de14d7

	recursor:
	forward-zones:
	- zone: example.org

pdns/pdns/recursordist/settings/table.py

Lines 1089 to 1091 in 3de14d7

	recursor:
	forward-zones:
	- zone: example.org

Regards,
Bernd
