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/bme280-python -b patch-boilerplate-sync
cd bme280-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.)

For the reasons behind these changes and other information, see:

• https://github.com/pimoroni/boilerplate-python/pull/13
• https://github.com/pimoroni/boilerplate-python/issues/16
• https://pimoroni.github.io/venv-python/

Changes

• CI: Update GitHub Action versions.
• QA: Add shellcheck and fix/ignore all issues.
• install.sh: slightly better feedback for setup commands.
• install.sh: fix quoting bug in do_config_backup.
• install.sh: don't output printf commands.
