Documentation for route-domains and dynamic routing protocols

In https://clouddocs.f5.com/products/extensions/f5-declarative-onboarding/latest/declarations/network-objects.html it uses "routingProtocols": [ "BGP" ], in the example routeDomain declaration, but that is apparently not compatible with the RoutingBGP or other declarations described in https://clouddocs.f5.com/products/extensions/f5-declarative-onboarding/latest/declarations/network-objects.html#configuring-bgp-routing-in-a-declaration due to the error "Cannot mix routing-protocol Legacy and TMOS mode for route-domain" described in https://github.com/F5Networks/f5-declarative-onboarding/issues/287
