Blog about DataFusion correlated subquery support

[alamb]

Is your feature request related to a problem or challenge?

This will serve as the final report / writeup for our Google Summer of Code 2025 project

• [Epic]: Google Summer of Code 2025 Correlated Subquery Support #16059

This will serve both to draw more attention to DataFusion as well as demonstrate how well the project went

Describe the solution you'd like

The idea is to write a blog post on https://datafusion.apache.org/blog/ that summarizes:

1. The high level problem of running decorrelated subqueries
2. The results of the Summer project
3. A sketch of how it was completed (both technically and with others)

Describe alternatives you've considered

Code is in https://github.com/apache/datafusion-site

I suggest we start working on the post as soon as possible as it takes quite a while to write such content

@Adez017 -- thank you -- maybe you can help review the post. I think we need to do more of the work before writing a post about it so this probably can't start for another few weeks
