fix(release): return port from get_port for non-routable process types

Env Vars are stored in a Secret, where there is 1 secret per Release. This causes a situation where non-web/cmd proc types will overwrite the Secret data during deploys.
This is the only way possible (for now) since env vars are per Release and not per proc type
