🐛 determine joystick status by pid in resolve_v5_port

[AndrewLuGit]

Summary:

In addition to checking the description, also check if the pid is equal to 0x503 to determine if a device is a joystick in resolve_v5_port

Motivation:

The value of is_joystick is crucial to the functionality of the pros terminal, as if it is a joystick the controller must be switched to the download channel. On Windows computers, vex brains and controllers show up with a generic description of "USB Serial Device", unless you install the vex USB drivers, which gives them their proper names. This means that currently is_joystick returns False for controllers on Windows computers without the vex drivers, which breaks pros terminal on Windows.

Test Plan:

• test that pros terminal works over controllers on Windows computers
• test that nothing else has broken, e.g. uploading programs, pros terminal from brain, pros terminal on Linux and macOS
