Dotnet MSBuild: Get Property does not expand properties

### Describe the bug
Unlike building thee project or uses msbuild properties in `launchsettings.json` the dotnet cli command `dotnet msbuild --getProperty` does not expand properties correctly, which returns results that don't match other implementations.

### To Reproduce
```xml

@(Item)

```
Save that xml as `Example.target` and run ` dotnet msbuild Example.target --getProperty:DynamicValue` which will return `@(Item)` instead of the correct `1;2` like building the project or uses launch settings.

If you run `dotnet msbuild Example.targe -t:Print` you will see it output the correct value of `1;2`

### Fun Facts
- Rider had the same implementation as the dotnet cli and labeled it as a bug. I filled an issue with them https://youtrack.jetbrains.com/issue/RIDER-123106
