Cake Frosting WithCriteria Description

### Prerequisites

- [x] I have written a descriptive issue title

### Cake runner

### Cake version

5.0

### Operating system

Windows

### Operating system architecture

x64

### CI Server

_No response_

### What are you seeing?

The fix implemented in #4027 does not seem to work as implemented. The SkippedMessage property was added to IFrostingTask and it was also implemented there to return an empty string. IFrostingTask is implemented in FrostingTask but it has nothing in there to allow you to change the SkippedMessage property. This is the only level where you can change the SkippedMessage property and have it picked up when trying to reference it using IFrostingTask. I added a SkippedMessage property to my CleanTask I was creating and the message was not used when the following is called in FrostingEngine

```
// Is the criteria method overridden?
if (task.IsShouldRunOverridden(_context))
{
cakeTask.WithCriteria(task.ShouldRun, task.SkippedMessage);
}

```

I made a small test project to verify this. Unless I am missing something I think this needs changed.

### What is expected?

Want to be able to set the skipped message for the WithCriteria like you can when using Cake Tool.

### Steps to Reproduce

Just try to set the SkippedMessage so it can be used when using the ShouldRun override.

### Output log

No error log to show the message does not show up.

Trace SkippedMessage from IFrostingTask through FrostingTask and into FrostingEngine, focusing on the WithCriteria call shown in the issue. Reproduce the behavior with a Cake Frosting task that overrides ShouldRun and sets SkippedMessage, then verify that the configured message is used rather than an empty value.
