[DOC] - SIP > SIP Settings is no longer available in dashboard, affecting FusionPBX documentation

[ChrisKlacsanzky-SignalWire]

Describe the requested update
Doc: https://developer.signalwire.com/platform/integrations/pbx-systems/connect-fusionpbx-with-signalwire/#creating-a-sip-endpoint

This section could be corrected as SIP > SIP Settings tab in dashboard is no longer there:

"Proxy Address
The Proxy address and other SIP credentials can be found in the SignalWire Dashboard by going to the SIP > SIP Settings tab as shown below."

Newer accounts don't seem to have this section, and older accounts had this SIP settings tab moved to 'Configuration' section.

Reason for the request
Dashboard changes
