feat: make code compatible with latest franka_ros version

This commit guarantees that the `panda_gazebo` code aligns with the most
recent upstream commit (specifically
5f90395ef000e0c998fb7aff8f127b9bd3773962). Adjustments were made to the
joint position and joint effort control services to integrate with the
updated version seamlessly. In the new iteration, the panda arm joint
positions and efforts are managed through group controllers. You can
find additional insights at
frankaemika/franka_ros#181 (comment).
