Subject: [PATCH] chore: migrate CI workflows to ubuntu-slim for faster startup
 times (#4007)

*This type of runner is optimized for automation tasks, issue operations
and short-running jobs. They are not suitable for typical heavyweight
CI/CD builds.*
[[1](https://docs.github.com/en/actions/reference/runners/github-hosted-runners#single-cpu-runners)].

We are not necessarily dependent on faster startups, but that seems to
be becoming the best practice now.
