Scaffolding razorpages fails when Model filename ends in "Program"

### Is there an existing issue for this?

- [X] I have searched the existing issues

### Describe the bug

When running the dotnet-aspnet-codegenerator utility, generator fails when the model used ends with the word "Program".

For example:

I have a model called DiplomaProgram.cs

If I run:
dotnet-aspnet-codegenerator razorpage -m DiplomaProgram -dc ExampleContext -udl -outDir Pages/DiplomaPrograms --referenceScriptLibraries

An error occurs described in the exception area.

If I change the filename to anything other than a name ending in "Program", command works as expected.

### Expected Behavior

Scaffolding tool should produce the Pages based on the model

### Steps To Reproduce

_No response_

### Exceptions (if any)

Building project ...
Finding the generator 'razorpage'...
Running the generator 'razorpage'...
Sequence contains no elements

### .NET Version

6.0.1

### Anything else?

The error is definitely tied to the fact that the model filename ends in "Program".....even if it's a compound word like "FooProgram"
