tools/ci: Include fetching pico-sdk in the CI environment setup

The Raspberry Pi pico-sdk was not available in the CI build process,
so the test builds for the rp2040 and rp2350 uCs could not execute the
last packaging stage. The SDK is now fetched and included, both at
runtime and in the Docker image.
