update find_available_ports to use serial.tools.list_ports

[meetsitaram]

What this does

Update dynamizel.py::find_available_ports to detect usb port connected to the dynamixel servos in multiple platforms - windows, mac and linux. The current approach of using Path("/dev").glob("tty*") was unable to detect ports in windows.

How it was tested

I tested the logic by running on a pc, mac as well as a linux virtual machine and was able to detect the port on all three platforms.

• windows detected COM5
• mac detected /dev/cu.usbmodel585A00081751
• linux virtual machine detected /dev/ttyACM0

How to checkout & try? (for the reviewer)

This can be tested only when running the dynamixel script while connecting and disconnected the usb device.

python lerobot/common/robot_devices/motors/dynamixel.py

@meetsitaram Thanks a lot for your PR, and for testing it on Mac, Linux and Windows.

We will work on merging it as soon as we added Continuous Integration on these 3 environments.

As of now we run CI on Linux only.
