Bookworm/Pi5 Compatibility: Upgrade to latest boilerplate

[Gadgetoid]

Testing

If you're a Bookworm / Pi 5 user running into virtual environment issues, you can try this library like so:

git clone https://github.com/pimoroni/trackball-python -b repackage
cd trackball-python
./install.sh --unstable

The ./install.sh script will create a pimoroni virtual environment that's shared between our products. (or use your existing venv if you've already activated one.)
