Summary

updated docs for slurm_partition, rebuild rd docs according to discussion in #25

I also checked the example in #25 against the latest {crew} 0.6.0.9000 build 56741ae and it resolved the issue with map(). I can confirm that the partition selection is working as intended :)

I see, missed that you changed it in main already. My bad.
