Use explicit kotlin-stdlib and kotlin-test versions from version catalog (#2818)

Using explicit versions helps work around the issue where the stdlib version was missing from the POM (https://youtrack.jetbrains.com/issue/KT-71443/Unexpected-POM-file-change-when-updating-from-Kotlin-2.0.0-to-Kotlin-2.0.20).

Also, simplify dependencies' setup since `stdlib-common` does not have to be declared explicitly since 1.9.20 (https://kotlinlang.org/docs/whatsnew1920.html#easier-configuration-of-new-standard-library-versions-in-gradle) and kotlin-test-junit is selected automatically if no other runner is specified (https://kotlinlang.org/docs/gradle-configure-project.html#jvm-variants-of-kotlin-test).

Fixes #2810
