Fix KSP tasks dependencies

[alexander-yevsyukov]

This PR updates KspBasedPlugin class so that it configures the dependency between kspKotlin tasks and launchSpineCompiler tasks via mustRunAfter() instead of dependsOn(). The latter proved to be unstable between the builds which has to do with parallelism of task configuration and execution.

Also, the latest KSP Gradle Plugin is now used for the build.

Pull Request Overview

This PR addresses task dependency configuration issues in the KSP-based plugins by switching from dependsOn() to mustRunAfter() for kspKotlin and launchSpineCompiler tasks. The change resolves stability problems related to parallel task configuration and execution. Additionally, the PR updates the KSP Gradle Plugin to version 2.2.20-2.0.4 and bumps the project version to 2.0.0-SNAPSHOT.019.

• Replaced dependsOn() with mustRunAfter() in KspBasedPlugin for task ordering
• Updated KSP Gradle Plugin from 2.1.21-2.0.1 to 2.2.20-2.0.4
• Removed explicit task dependencies from build scripts where handled by plugin
