Get the teslalogger and webserver images up in https://ghcr.io registry

[githubbiswb]

Is your feature request related to a problem? Please describe. Having uses use the docker build commands requires another step that is harder to over come, putting things in the ghcr.io registry lets them just enter the image: line in compose just like mariadb and grafana work

Describe the solution you'd like Push the images into the ghcr registry

Describe alternatives you've considered You can also use quay.io or docker hub, but I think ghcr makes the most sense since the project is here already and quay and docker hub come with complications

You also might consider switching the webserver to a standard image very available as images, such as nginx

Additional context Great project!
