Move dependencies to a Gradle version catalog

[fejd]

Is your feature request related to a problem? Please describe.
Gradle version catalog (https://docs.gradle.org/current/userguide/platforms.html#sub:central-declaration-of-dependencies) is a somewhat new feature where dependencies, versions, bundles and plugins are declared in a .toml file and then referred to in the build.gradle file as, for example libs.kotlin and libs.plugins.kotlin.kapt.

Describe the solution you'd like
Move dependencies in build.gradle to a libs.versions.toml file.

Describe alternatives you've considered
Having dependencies in buildSrc is one option. Version catalog is more of a "native" Gradle feature.

Additional context
The version catalog may not be supported by automated dependency update bots yet.
