Adapt gerrit_plugin rule to removal of resource_jars attribute

In Bazel release 5.0 resource_jars attribute was removed: [1]. Apply the
same fix that core did in Change I3b49112b65a4.

Preserve the attribute as-is to not change the caller sites and pass in
the resource jars collection to runtime_deps as recommended.
