set `strategy.fail-fast: false` for GH Action matrix jobs

Unfortunately, the GitHub Actions environments are too unreliable to have `fail-fast: true` making sense. I find myself constantly rerunning jobs, because some URL was supposedly not reachable to download some dependency. Rerunning the job always solves the problem. Since this usually only affects one or two jobs out of the whole matrix with > 20 jobs it makes sense to just let all jobs run to the end instead of cancelling them, then just rerun the failed jobs. Hopefully, one day the environment will be stable enough to eliminate these mistakes, but by now I have waited for over a year for things to get better.
