Release 2.0.0

🥳 🥳 🥳

This is a major release of Diktat, tailored to align with the global changes in the Kotlin ecosystem and the introduction of Kotlin 2.0. Our focus has shifted towards the Kotlin 2.0 compiler plugins, FIR and new IR, encompassing extensive preparatory efforts.
This includes:

• the introduction of a new CLI driver, independent from ktlint;
• transitioning from Maven to Gradle;
• crafting new Gradle and Maven plugins;
• refactoring, including the change of the package name: from org.cqfn to com.saveourtool;
• migrations to latest Kotlin and Ktlint;
• more than 25 fixes, requested by the community.

These initiatives aim to streamline our future development processes, simplifying the creation of new rules, while concurrently enhancing the complexity and precision of existing rules.
