fix(rviz config): remove initial_pose_button_panel

[YamatoAndo]

Description

#4848
rviz reports the following error:

[rviz2-74] [ERROR 1693558088.618417957] [rviz2]: PluginlibFactory: The plugin for class 'tier4_localization_rviz_plugin/InitialPose

This plugin was removed #4519.
So I will also remove tier4_localization_rviz_plugin/InitialPoseButtonPanel from the rviz cofings.

Tests performed

I have confirmed that no errors occur when launching RViz with each rviz config file.

like this.
ros2 run rviz2 rviz2 -d src/universe/autoware.universe/planning/obstacle_avoidance_planner/rviz/obstacle_avoidance_planner.rviz

Effects on system behavior

Not applicable.
