`element_invalid_self_closing_tag` triggers on `<enhanced:img />`

[ottomated]

Describe the bug

When using @sveltejs/enhanced-img, the <enhanced:img /> tag triggers this warning:

Self-closing HTML tags for non-void elements are ambiguous — use `<enhanced:img ...></enhanced:img>` rather than `<enhanced:img ... />`svelte(element_invalid_self_closing_tag)

Svelte should identify the custom namespace and suppress the warning here.
