ROS2PoseControl documentation issues

[pawelbudziszewski]

There are some issues with the documentation of the ROS2PoseControl:

General

• Please use passive voice: "the software can be used to..." instead of "you can use the software to...".

Adding component

• Attach it to the the entity you wish to control, at the to level or on the same as rigid body if one is present - it is a bit hard to understand
• I'd avoid referencing rigid body in these instructions - this asset SHOULD NOT have any rigid bodies (at least not active ones)
• I'd avoid referencing tractors - this gem is not specific to agri

Configuration

• The screenshot is outdated

Disabling physics based movement

• You might need to set Rigid Body type to kinematic - I'd put it stronger, something like: If there are any rigid body components, they should be removed or switched to kinematic

This, and previous changes should be enough to resolve this https://github.com/RobotecAI/robotec-o3de-tools/commit/9bef1fcb95980c65fd5deb7404e7294af0fafbb1
