warmupStrategy: false still creates a preload link

[lukas-pierce]

🐛 The bug

When using useScript() with warmupStrategy: false, Nuxt Scripts still adds a <link rel="preload"> tag for the script.

In the reproduction, lodash is loaded only as an example script:

useScript(
  {
    src: 'https://cdnjs.cloudflare.com/ajax/libs/lodash.js/4.17.21/lodash.min.js',
  },
  {
    warmupStrategy: false,
  }
)

Even though warmupStrategy is explicitly set to false, the page still contains a preload link for lodash.

The reproduction checks this with XPath and shows:

preloadFound: true

This seems inconsistent with the documented/type behavior where false should disable preloading.

I think the issue may be caused by this runtime check:

if (!options.warmupStrategy) {
  options.warmupStrategy = "preload";
}

Since false is a valid value for warmupStrategy, this condition treats false the same as an unset value and overrides it with "preload".
It probably should only apply the default when warmupStrategy is undefined.

🌈 Expected behavior

When warmupStrategy: false is passed to useScript(), Nuxt Scripts should not add a <link rel="preload"> tag for that script.

Expected result in the reproduction:

preloadFound: false
