publish container fills up the /tmp/Containers/Content directory over time

### Describe the bug

When I publish a container from an ASP.NET Core project on a Linux machine using self-hosted Azure Pipelines, the `/tmp/Containers/Content` directory fills up with data over time until my disk is full.

### To Reproduce

We are publishing containers using this command running on a Linux machine:
```
dotnet publish MyProjectName --configuration Release --os linux --arch x64 \
-p PublishProfile=DefaultContainer \
-p ContainerRegistry=my.container.registry.hostname \
-p ContainerRepository=my-container-name \
-p ContainerImageTag=$VERSION
```

### Exceptions (if any)
after many runs my disk gets full.

### Further technical details
.NET 8

I found this reference to the path: https://github.com/dotnet/sdk/blob/main/src/Containers/Microsoft.NET.Build.Containers/ContentStore.cs

But I did not find a reference to anything that can delete the temporary files created here.

As a workaround I am currently deleting the contents of `/tmp/Containers/Content` manually at regular intervals.
