build!: EXPOSED-315 Use the slimmer `spring-boot-starter-jdbc` instead of `spring-boot-starter-data-jdbc`

Youtrack: EXPOSED-315

• Exposed needs the underlying dependency to set up the JDBC, which it gets from simply the -jdbc dependency.
• The -data-jdbc also comes with an entire Repository-based programming model that is an ALTERNATIVE to Exposed, and Exposed does not actually need it
  • It includes things like CrudRepository and @Id annotations etc meant when using a specific programming model
• Therefore it makes sense to omit to have fewer constructs pulled in.

Unsure if this should be marked with fix/feat or similar, or whether this should be considered a breaking change or not. it's a breaking change in the sense that you lose some transitive dependencies, but it does not break the behaviour of API of Exposed itself.

@bystam Thanks for the PR! We'll label it as a breaking build change, just to be safe in the event users were relying on any transitive dependencies and will need to edit their build files.

Of course! Thanks for the quick feedback and allowing me to contribute 😄
