Fix console reference client cli args conflict

[mohdfareed]

Proposed changes

Attempted to run the ConsoleReferenceClient.csproj using the following:

cd Applications/ConsoleReferenceClient
dotnet build ConsoleReferenceClient.csproj --framework "net10.0" --configuration Release
./bin/Release/net10.0/ConsoleReferenceClient -h

Got the following output:

OPC UA Console Reference Client

Arguments f|file and f|fetchall conflict. Renamed the latter to fa|fetchall. The above exception is resolved.
