Is this a new feature request?

Wanted change

Would you be so kind to add a section on a docker compose healthcheck in the readme.me

Reason for change

it took me a while crawling the internet, grabbing bits and pieces all around on obscure fora to get the information.
And a docker healthcheck is quite a common thing in modern solutions.

Proposed code change

Docker Compose healthcheck

After running the bazarr container without a healthcheck, access the gui and read out the api key.

Add a docker secrets file, as mentioned above, or add a line to the .env file.

BAZARRAPIKEY=yourapikey

Then add the healthcheck section to to the docker compose file and restart the container.

The env_file lines are optional, as a docker compose container should always look for a .env.

services:
  bazarr:
    image: lscr.io/linuxserver/bazarr:latest
    container_name: bazarr
    env_file:
      - ./.env

    restart: unless-stopped
    healthcheck:
      test: ["CMD-SHELL", "curl -sSf http://127.0.0.1:6767/api/system/status?apikey=$$BAZARRAPIKEY || exit 1"]
      interval: 30s # n° seconds to initially wait before executing the health check + frequency of subsequent health checks.
      timeout: 10s # n° of seconds Docker awaits for your health check command to return an exit code before declaring it as failed.
      retries: 5  # n° of consecutive health check failures required to declare the container as unhealthy.
      start_period: 30s  # wait before starting the healthcheck after container launch

Personally I don't think it's right to have this part of a containers readme as this is more general practice on how to use healthchecks with any container.

I would be surprised if this documentation wasn't already in docker composes documentation.

The TZ throws error for me and wants different format:
If you build the docker with this compose it will run the file but throw an error not liking the TZ= says not compatible wants you to use - TZ=America/New_York type format.
