Reduce copy from 6.8 about page

[JeffPaul]

In finalizing the ​6.8 announcement post it was identified that some of the copy in the 6.8 About page needed to be removed.

Specifically, in the "A release polished to a high sheen." section at the top of the About page we need to change from:

Speculative loading speeds up navigation by preloading links before users navigate to them, while bcrypt hashing strengthens password security automatically.

Behind the scenes, database optimizations improve performance, and a new security warning system helps prevent vulnerabilities before they become a problem.

to:

About Page: Reduce copy on 6.8 about page.

In finalizing the 6.8 announcement post (​https://wordpress.org/news/2025/04/cecil/) it was identified that some of the copy on the 6.8 about page is not an accurate description of what is in 6.8. This copy is receiving a game misconduct penalty and automatic ejection. While the coach could bring on a substitute, a line change is the better option here.

Fixes #63323.
