Documenation updates

[JQuilty]

I've added documentation on where exactly various directories and files are on specific systems. I was able to test with various Linux distros as well as Windows. Unfortunately, I do not have a Mac available at this time to test where the files on MacOS are.

I can provide macOS paths in a few hours.

@anthonylavado

Were you able to get the paths for macOS?

[anthonylavado]

For the current version of Jellyfin (these will change in future at an undetermined date), these are the paths. As macOS is a BSD derivative, it follows the XDG paths.

Data: ~/.local/share/jellyfin
Cache: ~/.cache/jellyfin
Config: ~/.config/jellyfin
Transcode: ~/.local/share/jellyfin/transcodes
Web (is embedded in the .app shipped in the .dmg): /Applications/Jellyfin.app/Contents/Resources/jellyfin-web
Logs: ~/.local/share/jellyfin/log

Approved, but pending addition of the MacOS values cc @anthonylavado

@JQuilty can you fix the linter issue and add the MacOS paths, so we can merge this?
