Merge #598

598: GitHub Actions: bump actions/checkout and actions/cache to v3 r=rtwalker a=rtwalker

We're seeing  a lot of deprecation warnings on our CI runs lately e.g. https://github.com/timescale/timescaledb-toolkit/actions/runs/3359573483

which point to this [blog post](https://github.blog/changelog/2022-10-11-github-actions-deprecating-save-state-and-set-output-commands/) about deprecations in some GitHub Actions commands.

Bumping the checkout and cache actions appears to make many of these warnings go away.
