Avoid using `compile` configuration to declare dependencies in gradle build scripts

[eparovyshnaya]

Currently on an exercise build Gradle reports a warning on the topic: compile configuration has been marked as deprecated for further removal.

Suppose we should substitute it with implementation in _template-ed and applied build scripts.

The compile configuration has been deprecated for dependency declaration. This will fail with an error in Gradle 7.0. Please use the implementation configuration instead.

Absolutely! compile() is still used in build-configuration because it's required for current implementation of compileStarterSourceKotlin task (used in unit tests). This dependency should be reimplemented or fixed before using implementation().
