Replace `require` with `import` for images on the homepage

[obulat]

Problem

We use require for images on the homepage. require will be deprecated in Nuxt 3.

Description

We should move the hompage_images folder (images only, not the json file) to /static folder, and use the static URLs.

Change the code above to

src: `/homepage_images/${imageSet.value.key}/${idx + 1}.png`
