moduleDetection force compiler setting does not work

[souporserious]

Describe the bug

Version: 25.0.0

To Reproduce

Create a simple project setting moduleDetection to force which should treat each source file as a module:

import { Project, ts } from 'ts-morph';

const project = new Project({
  compilerOptions: {
    module: ts.ModuleKind.ESNext,
    moduleDetection: ts.ModuleDetectionKind.Force,
  },
  useInMemoryFileSystem: true,
});

project.createSourceFile('a.ts', `const a = 'a'`);
project.createSourceFile('b.ts', `const a = 'a'`);

project.getPreEmitDiagnostics().forEach((diagnostic) => {
  console.log(diagnostic.getMessageText());
});

However, this will not work as expected and produce type errors. Here is a StackBlitz Node.js project reproducing the issue along with using the TypeScript compiler directly which works as expected.

Expected behavior

The moduleDetection compiler setting should be respected and not produce diagnostics when set to force.
