Adopt CategoryTree for determining Recipe categorization

[sambsnyd]

rewrite-core now has a CategoryTree class that can make hierarchies of categories and recipes:
https://github.com/openrewrite/rewrite/blob/master/rewrite-core/src/main/java/org/openrewrite/config/CategoryTree.java

This project should adopt this approach as

• It will help with consistency with the saas
• It supports recipes in no category, such as RenameFile, which this project currently doesn't know how to support
• No need to duplicate the logic here now that it is available in rewrite-core

Came up briefly in this Slack thread:

Is there a way to do reverse loop up, i.e. given a recipe can I find out what different composite recipes is that recipe part of? Why I am asking this.. I am running the composite recipe (UpgradeSpringBoot_3_0) for migrating to springboot 3.0. Based on the results I am not sure if its including recipes for a) migrating to spring framework 3.0 and b) migrating HandlerInterceptorAdapter. (edited)

Might be worthwhile as part of this effort to also point out recipes not included into any composite recipes, such that it's easier to spot which can only be run as a one-off recipe run. Could help surface recipes that were added, but not included before.

Came up once again on Slack

I learned that recipes are "nested" in other recipes. Would it be possible not to list containment, but also contained-in on moderne? For instance, https://docs.openrewrite.org/recipes/java/migrate/lang/stringformatted should list that it is contained in UpgradeToJava17.
