Escape nested template literals in CircuitPreview snippet

The new circular board example embeds template literal syntax inside the string passed to code={ without escaping the inner backticks. The sequences width={ and height={ at this location close the outer template literal, so the MDX file is no longer valid JavaScript/JSX and Docusaurus will fail to compile the page. The inner template strings should escape their backticks (e.g., width={\${radiusMm * 2}mm`}) so the entire example remains inside the code` string.
