Use Gradle's Version Catalog

In order to improve our build and dependency version management, we should use [Gradle's Version Catalog](https://docs.gradle.org/current/userguide/platforms.html).

This is also a [prerequisite for using Dependabot](https://docs.github.com/en/code-security/dependabot/dependabot-version-updates/about-dependabot-version-updates#gradle)
