Remove jcenter from the list of dependency repositories

[petertrr]

What's done:

• Removed jcenter from pom.xml and build.gradle.kts

jcenter will be shut down soon; it was originally introduced in diktat for using dokka, but is probably no more needed

What about src/test/resources/test/smoke/build.gradle_.kts this path?

That's just a resource for smoke testing. This script is never actually executed.
