Add Docker support for building and installing jellyfin-tizen.

Description

This PR introduces Docker support for building and installing the jellyfin-tizen application.

How it works

1. Add your Samsung certificate to the relevant directory.
2. Enable developer mode on your Samsung TV.
3. Build the Docker image using the provided Dockerfile.
4. Run the Docker container with the certificate's password and the TV's IP address.

Caution

I have only tested this on Arch Linux/EndeavourOS. Testing is needed on Windows.
