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.

Merges [60183] to the 6.8 branch.
