unicorn: set registry.certificate.key to registry-auth.key
This lines up the default value for registry.certificate.key
to the naming convention throughout the rest of the charts and documentation, around registry-auth.*
The .gitlab-ci.yml
was covering the fact that this item was different, as well as doc/example-config.yaml
providing this value covered the fact that it was not needed thanks to the default values.
Corrects the miss from !50 (merged)
Relates to #127 (closed)
