Update MVC F# project template to resolve deprecated warnings

This is a follow-up to #68841.

We obsoleted all overloads of AddRazorRuntimeCompilation, but we missed one use in template code for F#.

Description

We missed a use of an obsolete API in F# template. This PR updates the template to drop the obsolete call.

Fixes #69113

Customer Impact

Template output today compiles with a warning. We want customers to have clean builds when creating a new project from templates.

Regression?

Yes, from #68841. The template used to compile cleanly without any warnings. Now it does have a warning.

Risk

Low.

This is a template change only and removes a call to an obsolete API.

Verification

A template test added. Ideally, we should enhance our tests in the future to actually build the project and ensure that it has no warnings. This hasn't been done as part of this PR though.

🟢 Approval recommended

The changes cleanly remove the deprecated runtime compilation usage, and the updated template tests validate the absence of the package/API in generated output.

Pull request overview

This PR updates the MVC F# project template to match the C# template by removing Razor runtime compilation usage, eliminating the FS0044 deprecation warning introduced by the obsolete runtime-compilation API/package.

Changes:

• Removed the Microsoft.AspNetCore.Mvc.Razor.RuntimeCompilation package reference from the F# MVC template project file.
• Removed the .AddRazorRuntimeCompilation() call from the F# template’s Program.fs.
• Updated MVC template tests to ensure runtime compilation is not emitted in generated projects and added an F#-specific assertion for Program.fs.
