Updated requirements to use ROS2 messages 3.3.2

[gremigi-bdai]

In this PR I'm updating the requirements for the spot_ros2 installation script to download and install the debian packages containing the ROS2 messages for Post SDK 3.3.2.

spot_wrapper is a submodule of spot_ros2 package and this PR must be approved before the following:

bdaiinstitute/spot_ros2#177

I will approve this but I think there's a significant amount of stakeholders to notify about this change.

Is this a breaking change? I know the BD protos are supposed to be backwards compatible.

They list the breaking changes in their release notes. These are the only ones.

When the robot loses connection with an E-stop endpoint, an attempt to power on the robot will now return STATUS_KEEP_ALIVE_MOTOR_OFF instead of STATUS_ESTOPPED. In python code it will raise the KeepaliveMotorsOffError exception instead of EstoppedError.

Some malformed Graph Nav graphs were previously accepted, but would leave the service in a bad state. These graphs are now explicitly rejected during upload.

I have searched for both STATUS_ESTOPPED and EstoppedError in both spot_ros2 and spot_ros. Neither repo has them explicitly.

My very basic testing hasn't had issues so far, but it's by no means comprehensive.
