Regression: HTTPS compatiable worker.

Please add an example on how to use HTTPS, or defer in the documentation it is no longer available. At somepoint this configuration was working. ```nix services.buildbot-worker.masterUrl = "https://buildbot.somewhere.com"; systemd.services.buildbot-worker.environment = { # If use self-signed certs, we must use our own # CA authority list, (curl & requests ship their own by default) CURL_CA_BUNDLE = lib.mkDefault "/etc/ssl/certs/ca-certificates.crt"; REQUESTS_CA_BUNDLE = lib.mkDefault "/etc/ssl/certs/ca-certificates.crt"; }; ``` While updating to the latest version, the endpoint schema changed. `services.buildbot-worker.masterUrl = "ssl:host=buildbot.somewhere.com:port=443";` The following error is reported. ``` root@somewhere ~# journalctl -ru buildbot-worker.service Jan 21 02:31:24 somewhere systemd[1]: Started Buildbot Worker..
