Use version catalog for storing dependencies

[bejibx]

Minified version of #50 with only libs.versions.toml support

[bejibx]

There is one place where version catalog can not be used:

akkurate/buildSrc/src/main/kotlin/akkurate.kmp-library-conventions.gradle.kts

Line 25 in fb143b3

implementation("org.jetbrains.kotlinx:kotlinx-coroutines-test:1.9.0-RC.2")

I'm suggesting to instead explicitly declare this dependency in every place where convention plugin is used

Thank you for this PR! 🙏 Could you add the missing comment?

I think you're right for kotlinx-coroutines-test, we can import it everywhere we need to keep the version inside the catalog. (I can write the commit if you want)

[nesk]

Could you add a comment here to explain what this code does?

Will do
