ci: modernize github actions (#1287)

- use `ubuntu-22.04` runner instead of `ubuntu-20.04`
- use `windows-2022` runner instead of `windows-2019`
- use `pnpm/action-setup` instead of handling `pnpm install` manually
- use pnpm-lock.yaml as caching key for actions/cache instead of inexistent package-lock.json
- define `packageManager` config option in `package.json` which is read by `pnpm/action-setup`
