fix(tag): allow on:close to work with Svelte 5

[metonym]

Fixes #2096

Interestingly, <Tag filter on:close /> does not fire because the forwarded on:click uses the stopPropagation modifier.

Removing it allows the dispatched "close" event to fire. on:close is effectively an alias for on:click, which is only forwarded to the button for a filterable tag.

Expected

Both "click" and "close" should be logged.

<Tag
  filter
  on:click={() => {
    console.log("click");
  }}
  on:close={() => {
    console.log("close");
  }}
>
  Tag
</Tag>

Expected

If the consumer manually stops propagation, "click" is logged but "close" will not. This works in Svelte 5, but not Svelte 4.

<Tag
  filter
  on:click={(e) => {
    e.stopPropagation();
    console.log("click");
  }}
  on:close={() => {
    console.log("close");
  }}
>
  Tag
</Tag>
