Fix expression parsing in foreign context

[Trombach]

Changes

• closes Generating <image /> elements inside an <svg> ends up with <img /> outside astro#13081

This PR adds the current Namespace to the expression Node.

When writing an expression inside foreign content (i.e. SVG) the astro compiler did not persist the namespace and therefore parsed the contained nodes in normal HTML mode. This lead to <image> tags incorrectly being transformed to <img> tags, but could also have caused other Problems.

Testing

• added printer test to validate correct parsing of {<image />} inside svg
