Revamped hosting guide needs to be ported

[mirrorcult]

i didn't do this yet as it likely needs to be thought out more and fully integrated with the current server hosting tutorials

im referring to the pages under /getting-started/server-hosting-rewrite-workspace on the wikijs docs, which were written by 20kdc i believe. the watchdog page is ported, but not the others, which have lots of useful information
