Add Dockerfile to build and run LibreTranslate as a Docker image. Also added a docker-compose.yml file to provide a reproducible way to run the Docker image. And finally added how to build and run the Docker image to the README.md. Tested with local deployment on port 5000 and public HTTPS deployment using a docker based nginx-proxy

+### Run with Docker
+
+Make sure you cloned the `models` submodule before building the Docker image:
+
+```bash
+docker build -t libretranslate .
+```
+
+Run the built image:
+
+```bash
+docker run -it -p 5000:5000 libretranslate [args]
+```
+
+Or build and run using `docker-compose`:
+
+```bash
+docker-compose up -d --build
+```
+
+> Feel free to change the [`docker-compose.yml`](https://github.com/uav4geo/LibreTranslate/blob/main/docker-compose.yml) file to adapt it to your deployment needs, or use an extra `docker-compose.prod.yml` file for your deployment configuration.
