Update dotnetisolated.* dependencies.

[EvanSchallerer]

The DurableFunctionsMonitor.DotNetIsolated NuGet package causes errors when installed alongside Microsoft.Azure.Functions.Worker.Extensions.DurableTask.SqlServer (version 1.5.2) due to conflicting dependency versions which are outdated in the DFM projects.

Repro Steps

• Create a new Azure Functions project in Visual Studio 2026
• Install Microsoft.Azure.Functions.Worker.Extensions.DurableTask.SqlServer Version 1.5.2
  • Build and run the project to verify that it works
• Install DurableFunctionsMonitor.DotNetIsolated version 6.7.3
  • Build project and note build errors that are difficult to work around.
