Recipe linking issues

[mike-solomon]

This applies to two recipes:

1. https://app.moderne.io/recipes/org.openrewrite.java.spring.boot2.MigrateDatabaseCredentials / https://docs.openrewrite.org/recipes/java/spring/boot2/migratedatabasecredentials

2. https://app.moderne.io/recipes/org.openrewrite.java.spring.PropertiesToKebabCase / https://docs.openrewrite.org/recipes/java/spring/propertiestokebabcase

The recipes that make up these recipes can not be found.

I'm not sure if this means these recipes just don't work - or if there is some issue with how we parse these recipes. I'm not sure if this is even an issue in rewrite-spring vs. OpenRewrite itself -- but wasn't sure where else to put this report.

I suspect part of the issue is that the recipe list is declared as subclasses https://github.com/openrewrite/rewrite-spring/blob/main/src/main/java/org/openrewrite/java/spring/PropertiesToKebabCase.java#L47-L49
