Inaccurate init method description in JointLimiterInterface.

[MARIANOCEREDA]

The docstring from the init method from JointLimiterInterface is a bit inaccurate.

In particular:

/**
   * Wrapper init method that accepts the joint names and their limits directly
   */
   ...
 virtual bool init(
    const std::vector<std::string> & joint_names,
    const std::vector<joint_limits::JointLimits> & joint_limits,
    const std::vector<joint_limits::SoftJointLimits> & soft_joint_limits,
    const rclcpp::node_interfaces::NodeParametersInterface::SharedPtr & param_itf,
    const rclcpp::node_interfaces::NodeLoggingInterface::SharedPtr & logging_itf)
    ....

This overload also takes soft_joint_limits, not just names and limits as mentioned in the docstring. For instance:

/**
   *  Wrapper init method that accepts the joint names, their limits directly, and the soft joint limits.
   */

Hi, I'd like to work on this fix.
I'll update the docstring to accurately reflect that this overload also accepts soft_joint_limits. Targeting main branch.
