Here are the MW pages that consist of the text "Blog posts": I'm guessing it's the second one, but you may want to change both of them just to be consistent.
 * MediaWiki:Category-exhibition-blogs-header
 * MediaWiki:Create-blog-post-category

For reference, I found these by going to Special:AllMessages, changing the limit to 5000, and searching the page. It takes a while to load but there are under 15,000 results, so it doesn't take too long to do. I'm not sure if there's a more efficient way of searching all the system messages.
