Chart: baseURL is set including "https" if not explicitly set

[kastl-ars]

Thanks for the nice chart, it is working (almost) perfectly!

One thing I noticed in my tests, which were done without TLS being enabled:

I could reach the planka ingress, but only got a white page. I found that the page's source code contained links to https://<hostname-from-ingress>. I could reach the site via https, but only because Traefik (my ingress controller) has a default TLS certificate.

Setting the baseURL to http://<hostname-from-ingress> allowed me to properly reach the page via HTTP.

I know this is a cornercase, but it might be worth a hint. Not sure if the baseURL can be properly derived with http or https, dependening on whether ingress.tls is set or not.

Kind Regards Johannes
