[Kavita] Rootless image

Idea Description

Hi, I am trying to setup Kavita for the first time. Noticed that by default it runs as root. It would be nice to be able to setup a custom user.
Tried to use the env PUID/PGID, but did not work.
Then tried the compose user field. It worked. It booted up, but in the logs I see this:

[Kavita] [2024-07-17 12:48:39.219 -03:00  1] [Error]  There was an error setting base url
System.UnauthorizedAccessException: Access to the path '/kavita/wwwroot/index.html' is denied.

   at System.IO.StreamWriter..ctor(String path, Boolean append, Encoding encoding)
   at HtmlAgilityPack.HtmlDocument.Save(String filename)

When using the root mode, that does not come up. I guess the image is not prepare to run under a different user. Not sure what is the impact of it, but in any case it would be nice to be able to get it working fine without root user.

You can use the LSIO image if you don't want to run as root. We removed that ability as it broke some NAS devices. We aren't interested in bringing it back with LSIO available.

Nice. That was the image I was looking for. Thanks!
