Tag Helpers not working in published site

### Is there an existing issue for this?

- [X] I have searched the existing issues

### Describe the bug

When running in the debugger, the "site.js" script tag successfully gets a hash appended to its query string (as expected), and the files matching the src-include have script tags generated for them. However, after publishing neither of these features work. It's unclear if any other tag helpers are working either. Tested running both in IIS and just running the EXE file generated by the publish.

```














```

### Expected Behavior

Tag helpers, specifically src-include, work in a published app the same as in development.

### Steps To Reproduce

1. Create ASP Core Web API project with ASP Identity
2. Override some Identity pages, including the main _Layout.cshtml. Leaving the existing markup is fine.
3. Make sure the new Layout page is used by adding:
```
@{
Layout = "/Pages/Shared/_Layout.cshtml";
}
```

To the _ViewStart.cshtml of the Identity area being overriden
4. (Optional) Add some script tags with asp-src-include

### Exceptions (if any)

_No response_

### .NET Version

6.0.203

### Anything else?

.NET 6, VS 2022.

Reproduce the published-app behavior using the Identity area override, _ViewStart.cshtml, and _Layout.cshtml described in the issue, comparing it with debugger output. Start by checking the rendering of the environment and script tags, especially asp-src-include and asp-append-version, in a .NET 6 published executable or IIS deployment. Done means the published app processes these tag helpers as it does during development.
