Sweep through all the articles to remove redundant ".NET Aspire"

Ah, yeah - this is a good callout. I want to sweep through all the articles and remove those where it's redundant.

We need to look at all articles (not includes) and evaluate whether we need to adjust their frontmatter data. For example, if an article contains:

---
title: .NET Aspire blah blah
<!-- omitted for brevity... -->
---

We might want to set the titleSuffix: "" which will remove the globally applied title suffix. The h1 doesn't need to match the title, but that's a common pattern. Alternatively, instead of removing the globally assigned suffix, you might want to remove ".NET Aspire" from the title where it makes sense.
