docker: remove SHELLHUB_REDIRECT_TO_HTTPS and simplify docker-compose

This commit removes the SHELLHUB_REDIRECT_TO_HTTPS variable from the
.env file and simplifies the docker-compose files.
The docker-compose.nossl.yml file is removed and the SSL_COMPOSE_FILE
variable in the bin/docker-compose script is updated to only include
the autossl suffix if SHELLHUB_AUTO_SSL is true.
