Update Axis Camera Discovery

I had an issue where newer Axis cameras were not being recognized properly. I believe the /includes/definitions/axiscam.yaml needs to be tweaked to match “Dome Camera” instead of “Network Camera.” I tweaked the line on my machine and it works fine. I don’t have github and I’m not sure I’d be able to stumble my way through a pull request, so I’m hoping someone can take the torch for the benefit of others.
