Can't handle referenced build properties for AssemblyName

## Current Behavior
We use the following definition in all our project files:
```
CycloneDxDotnet.Repro.WebApi
$(RootNamespace)
```

If you now reference multiple such projects in a main project, cyclonedx-dotnet throws an error:
```
Unhandled exception: System.ArgumentException: An item with the same key has already been added. Key: $(RootNamespace)

```

## Workaround
To work around this issue, you could set `AssemblyName` explicitly.
Reversing the reference of the build property is not a good solution because it can make problems in other tools (e.g. ReSharper):
```
$(AssemblyName)
CycloneDxDotnet.Repro.WebApi
```

## Reproduction
For reproduction use the added [solution folder](https://github.com/user-attachments/files/17990993/CycloneDxDotnet.Repro.zip) and execute:
```
dotnet CycloneDX .\WebApi\WebApi.csproj -o . -f WebApi.sbom.json --json --recursive
```

## Expected Behavior
Resolve referenced build properties for `AssemblyName` or detect such use cases and return a descriptive error message that cyclonedx-dotnet can't handle it.

## Environment
`dotnet cyclonedx --version`
```
4.1.0+3ad0483c8724b6ddd0c20506b034dde5f8555b44
```

`dotnet --info`
```

Start by reproducing the failure with the linked solution folder and the documented dotnet CycloneDX command. Inspect ProjectFileService.cs, especially RecursivelyGetProjectReferencesAsync at the reported line, and trace how referenced AssemblyName and RootNamespace properties are collected. Done means referenced build properties are handled or the duplicate-key case produces a descriptive unsupported-use error instead of an unhandled exception.
