This commit harmonizes dependencies used in smoke tests, in particular
by using the starters consistently. This serves not only as a validation
but also a showcase of how to use them.
Closes gh-47836
This commit moves the existing JDBC-based Spring Batch infrastructure
to a new 'spring-boot-batch-jdbc' module, while the existing module
only offers in-memory (aka resourceless) support.
The commit also updates the reference guide to provide some more
information about what's available and how to use it.
Closes gh-46307
