Upgrade to spring-javaformat 0.0.28 and downgrade to Checkstyle 8.41

In order to be able to use text blocks and other new Java language
features, we are upgrading to a recent version of Checkstyle.

The latest version of spring-javaformat-checkstyle (0.0.28) is built
against Checkstyle 8.32 which does not include support for language
features such as text blocks. Support for text blocks was added in
Checkstyle 8.36.

In addition, there is a binary compatibility issue between
spring-javaformat-checkstyle 0.0.28 and Checkstyle 8.42. Thus we cannot
use Checkstyle 8.42 or higher.

In this commit, we therefore upgrade to spring-javaformat-checkstyle
0.0.28 and downgrade to Checkstyle 8.41.

This change is being applied to `5.3.x` as well as `main` in order to
benefit from the enhanced checking provided in more recent versions of
Checkstyle.

Closes gh-27481
