[Enhancement] Healthchecks

[JerboaGobi]

I think there is a good use case for a /healthcheck endpoint to be added to the application. It would also idea to add a binary that can be used to verify the containers health during runtime or to extend the application so that it has a paramater that acts as the healthcheck. Lastly, to update the Dockerfile so that the healthcheck is performed.

Of what type of healthcheck are you referring to? To a healthcheck that tells whenever invidious-companion is blocked from Youtube? Or if it replies to the client (a simple http request to a /health endpoint that returns 200)?

The latter, http 200.
