### Current Behavior

The SelectAllTextBehavior cannot be referenced from a project that runs .NET without a native runtime. Because of the way unit tests run in Maui, it's common to have a version of .NET as the target framework.

Based on the initial PR for the docs highlighting the behavior (pun intended) https://github.com/MicrosoftDocs/CommunityToolkit/pull/411#issuecomment-2081680258

### Expected Behavior

You should be able to refer to `SelectAllTextBehavior` in a `net8.0` project target just like all other `Behaviors`.

### Steps To Reproduce

1. Open SelectAllTextBehaviorTest/SelectAllTextBehaviorTest.sln
1. Uncomment the Entry.Behavior in Project2/MyControl
1. Build the solution for a native runtime, I've been using iOS.
1. The build will fail saying Error: XLS0414: The type 'toolkit:SelectAllTextBehavior' was not found. Verify that you are not missing an assembly reference and that all referenced assemblies have been built.

### Environment

```markdown
- .NET MAUI CommunityToolkit: 8.0.1
- OS: macOS
- .NET MAUI: 8.0.x
```

### Anything else?

_No response_

Start with SelectAllTextBehaviorTest/SelectAllTextBehaviorTest.sln and Project2/MyControl, then reproduce the build after uncommenting Entry.Behavior for a native runtime. Compare that failure with a net8.0 target and the other Behaviors. Done means SelectAllTextBehavior can be referenced and the solution builds without XLS0414.
