docs(gpio): pin Jetson.GPIO >=2.1.12 and add loopback example#21

The apt-shipped python3-jetson-gpio doesn't recognize the Orin Nano Super compatible string (nvidia,p3768-0000+p3767-0005-super) and fails with "Could not determine Jetson model". Jetson.GPIO 2.1.12 on PyPI contains the fix; pin a >= constraint in both gpio-control.md pages (JAJ + PAB) so customers don't trip over this on a fresh device. Also replace the single-write Python example with a HIGH/LOW/HIGH/LOW toggle that reads each transition back, mirroring the loopback test in scripts/test_i2s_gpio_loopback.sh in ark_jetson_kernel.

Summary
sudo pip3 install 'Jetson.GPIO>=2.1.12'before using the GPIO Python example. The apt-shippedpython3-jetson-gpiopredates upstream Orin Nano Super support and fails withCould not determine Jetson modelon thenvidia,p3768-0000+p3767-0005-supercompat string. v2.1.12 on PyPI contains the fix.scripts/test_i2s_gpio_loopback.shinark_jetson_kernel.embedded-computers/, PAB underknowledge-base/).Related: ARK-Electronics/ark_jetson_kernel#60, NVIDIA/jetson-gpio#134.
Test plan
sudo pip3 install 'Jetson.GPIO>=2.1.12'then the example with a jumper from HDR40 pin 40 to pin 38; confirm four PASS lines.🤖 Generated with Claude Code
