This continues#20786 to do some minor tweaks.

1. We now display a full example of how to select the built-in styles.
2. The listing of built-in styles now provides more details.

Before, it was rendered like this (seehttps://symfony.com/doc/7.3/components/console/helpers/tree.html)

I think it's fine to remove the:method: link because it doesn't provide direct links to the method, just to the class. So, all the previous:methods: links were in practice the same link.
