Change Hl7.Fhir.Model.Task into FhirTask so it doesn't conflict with System.Threading.Tasks.Task

Because of the naming, code in that has a using Hl7.Fhir.Model; needs an accompanying using Task = System.Threading.Tasks.Task. This is tripping up some of our users that are trying out LLM generated code using the Firely SDK.

Yes, it's a nuisance in our code too. We are hardly ever using Task, yet including the Hl7.Fhir.Model namespace makes async C# give compile errors if yoiu don't carefully use aliases. It's of course a major breaking change, though one could wonder how many people of the SDK actually use Task (there will be some for sure) - but even they might agree ;-0

I'll discuss it with the team - and we should discuss this in the community as well. We're putting the finishing touches on SDK 6.0, so if we do it, it should be in that major release, otherwise we will have to wait for SDK 7.0, easily 18-24 months out.

I'll create a poll in zulip to start the conversation
