[feature request] additional blog metadata

[annthurium]

Low priority feature request for 2 additional pieces of blog metadata:

• the option for authors to add their pronouns. Not just for me personally, but because it helps signal that deepset values DEI which can be a differentiator.
• blog posts could have a "reviewer" as well as an "author." That way if someone makes suggestions but isn't a primary author, we can have a lightweight way to give them credit.

I'm not sure how much work these might take to implement.
