add kafka Spring starter smoke test

Fixes #11261

Previously we tested with the earliest supported version + latest. Now we test with latest 2.x and latest 3.x. Are you sure you wish to remove testing from the earliest supported version?

I don't get it

• previously we tested against
  • 2.7.18 in autoconfigure (latest 2.x)
  • 3.2.5 in smoke test (latest 3.x)
• now we're testing against the same versions - just in smoke test

Regardless - I'd like to tackle this comment in an upcoming PR 😄

we have the capability to test with earliest supported boot version, by using library dependencies, but looks like we aren't taking advantage of that capability and are just pinning the spring boot library dependencies to the latest 2.x and 3.x versions

	val springBootVersion = "3.2.4"
	library("org.springframework.boot:spring-boot-starter-web:$springBootVersion")

it's a good question though, as typically we test all the instrumentation against an "earliest supported version" (and document that as the earliest supported version).

we should decide if/how we want to test/support earlier Spring Boot minor versions, @zeitlinger can you open an issue? I'll go ahead and merge this PR
