No CURL or WGET in official image to enable health-check

[ysslang]

Describe the bug
There is a health-check api in jellyfin. However, it seems we can't check the status with official docker image.

System (please complete the following information):

• Virtualization: Docker
• Jellyfin Version: Docker latest image, 20210322

Expected behavior
Add curl or wget package to official docker image.

I added a PR to keep wget in image, but when would you need to debug with wget from inside the docker image and not from outside ?

We discussed this internally too because of the mentioned healthcheck endpoint (we'd really like to add this to the container). The problem that came up is the healt-check endpoint depending on the baseURL which is dynamically configured. We can't fix this without breaking current setups, so it'll most likely be a Jellyfin 11 thing.

Aside from the healtcheck I don't see any additional gain from including wget or curl into the images.

Thanks.
The purpose of healthcheck within container is restarting container while jellyfin crash. Since my host is a low end vps.

This command is capable to extract the base path and port from the config files:

curl http://localhost:$(grep -oP '(?<=PublicPort>)[^<]+' /config/config/network.xml)/$(grep -oP '(?<=BaseUrl>)[^<]+' /config/config/network.xml)health
