.NET 9 SDK introduces hang in `dotnet format` when run on Azure Pipelines in combination with NB.GV

### Describe the bug

`dotnet format --verify-no-changes --no-restore` just hangs with no output when run in this configuration:

- Azure Pipelines (local is fine)
- .NET 9 SDK (.NET 8 SDK is fine)
- With the Nerdbank.GitVersioning nuget package referenced

[Working fine with .NET 8 SDK](https://dev.azure.com/andrewarnott/OSS/_build/results?buildId=10813&view=logs&j=0da5d1d9-276d-5173-c4c4-9d4d4ed14fdb&t=d9b15392-e4ce-5e4c-0c8c-b69645229181)
[Hanging (across 2 attempts) with .NET 9 SDK](https://dev.azure.com/andrewarnott/OSS/_build/results?buildId=10814&view=logs&j=50a69d0a-7972-5459-cdae-135ee6ebe312&t=13df7b5c-76db-5c26-6592-75581a9ed64a)


@nietras [reported the same issue with their own repo](https://github.com/dotnet/Nerdbank.GitVersioning/issues/1119), who isolated the repro to requiring both .NET 9 SDK *and* the Nerdbank.GitVersioning package.

In my case, the hang is on a linux build agent. For @nietras I believe it was a Windows agent. Both of us run this tool only on one agent in the pipeline.
 
### To Reproduce

1. Fork the repo at https://github.com/dotnet/Nerdbank.Streams.git
1. Run it under Azure Pipelines on this commit: 09b404915c9a6d4566023e3bdebbbf8b08eebf42

### Exceptions (if any)

@nietras also shared the diagnostic output:
