Please maintain a changelog or GitHub releases

It's important for developers to review changes coming in whenever a dependency is updated, and for that we rely on changelogs to avoid the burden of reviewing a full git log and diff.

As suggested in docs, developers of libraries can integrate with Kotlin-Jupyter by depending on its Gradle plugin and test-kit artifact. But currently, the Kotlin-Jupyter CHANGELOG.md is not maintained since "0.11.0.170 (2022-10-05)", neither are GH releases published with a description.
