Plex on NixOS

I like your plex_media service, probably going to adapt it to my setup with disks on the local network.

I have plexpass and wanted to use the newer Plex server so I threw this overlay together: https://gist.github.com/iamevn/11952b966c05ca799f4910e02c2ff...

Just need to spin up a service that uses the included script to query the latest version info and then rebuild whenever there's a new Plex version.

Still new to Nix so would love any feedback on how readable it is. I figured it would be clearer to keep the json simple and have a shell script that pulls out the relevant fields out rather than parse things out directly in Nix.
