Drop duplicated dependencies from pom.xml

[yevhenii-nadtochii]

This PR addresses #362.

In particular, it does the following:

1. Deletes manual applying of pmd plugin, which is now applied via our pmd-settings script. It eliminates duplicated dependencies on pmd.
2. Pulls the latest config which contains a fix for the issue. It hides duplicated dependencies on protoc, emitting a warning.
3. Enables publication of dokkaJar artifact.

Additionally, J2ObjC.lib was replaced with J2ObjC.annotations, as the former is deprecated:

    const val annotations = "com.google.j2objc:j2objc-annotations:${version}"
    @Deprecated("Please use `annotations` instead.", ReplaceWith("annotations"))
    const val lib = annotations

Please note, when pulling the latest config, the versions of some libraries have been preserved as they were:

1. ErrorProne kept 2.10.0 due to Bump the versions of Spine libraries #181.
2. CommonsCli kept 1.4.0 due to Bump the versions of Spine libraries #181.
3. Protobuf kept 3.19.4 due to Bump the version of Protobuf #183.

The library version is bumped to 2.0.0-SNAPSHOT.74.
