[editorial] Inline Hugo front matter

[chalin]

• Context: [Editorial] suppress MD041 - First line in a file should be a top-level heading #4021 (comment)
• The proposal is to inline the Hugo front matter as actual YAML front matter rather than via an HTML comment. This will streamline publication to the OTel website, and avoid issues like [Editorial] suppress MD041 - First line in a file should be a top-level heading #4021
