Add `can_fd` argument to bringup launch arguments

[FrostyFridge]

Describe the feature you want

The openarm_hardware package has support for parsing a can_fd parameter, which defaults to true.

openarm_ros2/openarm_hardware/src/v10_simple_hardware.cpp

Lines 52 to 61 in 39dc03e

	// Parse CAN-FD enable (default: true for V10)
	it = info.hardware_parameters.find("can_fd");
	if (it == info.hardware_parameters.end()) {
	can_fd_ = true; // Default to true for V10
	} else {
	// Handle both "true"/"True" and "false"/"False"
	std::string value = it->second;
	std::transform(value.begin(), value.end(), value.begin(), ::tolower);
	can_fd_ = (value == "true");
	}

However, none of the launch scripts actually accept and pass along a can_fd argument. Therefore, users who are using CAN-2.0 instead of CAN-FD are unable to use the provided launch scripts without modification.

An additional can_fd argument should be added to all of the existing launch scripts, and passed along appropriately.
