APP_LOCAL_URL default incorrect in docs

[jrjake]

Description

On the Config Cheat Sheet, the default listed for [server] LOCAL_ROOT_URL is only correct when protocol is not fcgi/fcgi+unix/http+unix:

LOCAL_ROOT_URL: %(PROTOCOL)s://%(HTTP_ADDR)s:%(HTTP_PORT)s/: Local (DMZ) URL for Gitea workers (such as SSH update) accessing web service. In most cases you do not need to change the default value. Alter it only if your SSH server node is not the same as HTTP node. Do not set this variable if PROTOCOL is set to http+unix.

See the code here:

	var defaultLocalURL string
	switch Protocol {
	case HTTPUnix:
		defaultLocalURL = "http://unix/"
	case FCGI:
		defaultLocalURL = AppURL
	case FCGIUnix:
		defaultLocalURL = AppURL
	default:
		defaultLocalURL = string(Protocol) + "://"
		if HTTPAddr == "0.0.0.0" {
			defaultLocalURL += net.JoinHostPort("localhost", HTTPPort) + "/"
		} else {
			defaultLocalURL += net.JoinHostPort(HTTPAddr, HTTPPort) + "/"
		}
	}
	LocalURL = sec.Key("LOCAL_ROOT_URL").MustString(defaultLocalURL)

Looks like the logic is too complicated to change the documentation.
