Supersedes #35430
Summary
This PR reworks the mvc-jsp section following the review feedback:
<bean>declaration with a higher-level JavaConfigconfigureViewResolvers(ViewResolverRegistry registry)snippet as the default example.<mvc:view-resolvers>XML example within a note for legacy configuration.Motivation
As suggested in the review, this section is not the right place to document low-level defaults.
By focusing on configuration style and best practices, while still covering XML for legacy users, the documentation stays concise and aligned with Spring’s reference doc guidelines.
