Module not found in monaco-run even using monacoRunAdditionalDeps

[jesustorresdev]

Describe the bug

As described in #2186, monacoRunAdditionalDeps is ignored so the import of packages fails in monaco-run.

Minimal reproduction

1. Create a slide with monaco-run where some packages are impoted:

   ```ts {monaco-run}
   import { signal, effect } from '@angular/core';
   import { TestBed } from '@angular/core/testing';
   import { BrowserDynamicTestingModule, platformBrowserDynamicTesting } from '@angular/platform-browser-dynamic/testing';
   
   TestBed.initTestEnvironment(BrowserDynamicTestingModule, platformBrowserDynamicTesting());
   TestBed.runInInjectionContext(() => {
     const valueSignal = signal(1);
     console.log('Start');
     effect(() => {
       console.log('Signal:', valueSignal());
     });
   
     TestBed.flushEffects();
     console.log('After effect');
     valueSignal.set(1);
     TestBed.flushEffects(); 
     console.log('End');
   });
   

2. Add monacoRunAdditionalDeps to frontmatter:

monacoRunAdditionalDeps:
 - '@angular/platform-browser-dynamic'
 - '@angular/core'
 - 'rxjs'
 - '@/snippets/angular-testbed'

3. Install the dependencies in the project
4. Start the dev server and see the error "Module not found"

Environment

• Slidev version: 52.10.1

Possible fix

1. monacoRunAdditionalDeps is completely ignored in the code. I think something like this is needed to add the dependencies in monacoRunAdditionalDeps.

   const deps = uniq(data.features.monaco.deps.concat(data.config.monacoTypesAdditionalPackages).concat(data.config.monacoRunAdditionalDeps))

   I tested it and it works.

2. But that solution only allows using monacoRunAdditionalDeps in headmatter. The documentation talks about from matter. Maybe something like this could work:

   const perSlideDeps = data.slides.flatMap(slide => slide.frontmatter?.monacoRunAdditionalDeps || [])
   const deps = uniq(data.features.monaco.deps.concat(data.config.monacoTypesAdditionalPackages).concat(data.config.monacoRunAdditionalDeps).concat(perSlideDeps))
