Several tweaks and experiments with Gitlab CI

- made the runner name explicit (ubuntu-22.04 instead of ubuntu-latest)
- use checkout action v3 (not v2) - silences a Github warning
- attempted to cache dependencies
- reordered the actions a bit so that the cached items are handled first
- installed all dependencies to /opt/riscv so that they can be cached more easily as a bulk
