Overview
Updates the Spanish and French editor/collaborate.mdx pages to reflect collaboration via shareable editor links, including a new section documenting the editor URL format and usage.

Also tweaks metadata (description/keywords) and slightly expands the preview deployment copy to emphasize using previews for feedback; adds missing trailing newlines.
