Visual Studio 2022 Template "ASP.NET Core Web App" converts hyphens to underscores in _Layout.cshtml css href, causing 404 on the css when debug/run.

### Is there an existing issue for this?

### Describe the bug

Using Visual Studio 2022 Template "ASP.NET Core Web App", the new project converts hyphens to underscores in _Layout.cshtml css href for the css "isolation" file.

I know this seems minor but I (stupidly) spent a lot of time before I noticed the conversion of hyphens to underscores and I found a bunch of other issues related to css isolation here so thought this may help someone.

Note that command line `dotnet new razor` doesn't have this issue (which is how I found the resolution).

### Expected Behavior

Don't do that.

### Steps To Reproduce

Create new project using the above template with project named "test-asp-net-6-app". After project is created the stylesheet link is created with underscores instead of hyphens causing a 404 on the style sheet when running the app.

**_Layout.cshtml**
``


The build/runtime is expecting a style sheet file with hyphens: `test-asp-net-6-app.styles.css`
