add a udev rule for linux systems to access the pico without sudo

[diehard67]

I created a udev rules file so I can use picotool without sudo

# make raspberry pi pico accessible without sudo.

SUBSYSTEM!="usb_device", ACTION!="add", GOTO="rpi2_end"
# Raspberry Pi Pico
ATTR{idVendor}=="2e8a", ATTRS{idProduct}=="0003", MODE="660", GROUP="plugdev"

LABEL="rpi2_end"

I guess this is very similar to https://github.com/raspberrypi/openocd/pull/5 and https://github.com/raspberrypi/openocd/pull/27 ? (although not identical, as it has a different idProduct)

yah sort of, this one is for a pico in BOOTSEL mode, not picoprobe, but looks like the same goal.
