CSS container gives up warning

[andirady]

Describe the bug

All browsers listed in MDN now supports CSS container. When I use it in svelte, it gives warning in the language server & svelte-check.

Reproduction

<main>
   <div>Content</div>
</main>

<style>
  main {
    container-type: inline-size; /* this gives warning */
  }
  
  div {
    background: var(--bg);
    color: white;
    --bg: red;
  }
  
  @container (width > 728px) { /* this also gives warning */
    div {
      --bg: blue;
    }
  }
</style>

Expected behaviour

No warning.
