Have you had a look into the readme of teleop_twist_keyboard? You need to remap the topic, and take care that you use the same settings for the stamped version of the twist message: use_stamped_vel is default false on humble, but also the default for the teleop_twist_keyboard's stamped parameter.

The remap command is written in the first section of the readme, just use the topic necessary for the bicycle_steering_controller

ros2 run teleop_twist_keyboard teleop_twist_keyboard --ros-args --remap cmd_vel:=/bicycle_steering_controller/reference

If you have further questions, I suggest that you open a question on https://robotics.stackexchange.com/questions, because this topic is not related to our repository here.
