Allow Custom HTML Tag Assignment for Pages

Request:
Enable users to change the default HTML tag (currently always <div>) that wraps the Page content. This would allow better semantic control over top-level layout elements.

✅ Expected Behavior

• When editing a Page, users can choose a different HTML tag (e.g., <main>, <section>, <article>, <header>, etc.)

• This tag is reflected in the published HTML

• The tag can be selected via the Props Panel for the page

🎯 Why This Matters

• Improves semantic structure and accessibility

• Aligns with modern HTML practices (e.g., <main> for page content, <section> for grouped content blocks)

• Gives developers more control over final output without needing to wrap content manually

📌 Related Notes

• May also require visual indicator in the UI to show which tag is currently being used
