Depend on Flyway beans by type not name

Previously, a custom Flyway bean named anything other than flyway
could result in a NoSucBeanDefinitionException as the dependencies
set up for JPA and JDBC components used the bean name flyway.

This commit updates the configuration of the dependencies to depend
on Flyway beans by name rather than type.

Fixes gh-18102
