Blackbox_exporter manifest erroneously uses -config.file instead of --config.file parameter

[noroute]

The recently merged support for the blackbox_exporter contains a typo for the config.file parameter which is a long-form parameter in blackbox_exporter but erroneously passed as -config.file.

Actual behaviour: blackbox_exporter is started with -config.file=/etc/blackbox-exporter.yaml and bails out.
Expected behaviour: blackbox_exporter is started with --config.file=/etc/blackbox-exporter.yaml and works.
