Describe the bug

When using <svelte:element> with an xmlns attribute, we get a type error, even though the attribute should be allowed.

https://www.w3schools.com/xml/xml_namespaces.asp

Reproduction

Create a <svelte:element this="div"> that is not a svg element, and add the xmlns attribute to it and notice the type error.

Should be an easy fix within elements.d.ts
