This commit polishes the smoke test for Spring Web Services, namely
clearing unused dependencies and clarify the necessary configuration:
1. No need to extend from `WsConfigurationAdapter` if no advanced
configuration is required
2. Spring Web Services creates a `XsdSchema` bean whose name matches
the name of the file. Added a `@Qualifier("hr")` to make that more
obvious as it would break if an additional schema was to be added.
Closes gh-44515
