[Fix]: Property PhysicalContext is invalid "none"

Issue: Redfish validator is throwing error "PhysicalContext:
This type is invalid none" for multiple temperature sensors

Endpoint : /redfish/v1/Chassis/<Baseboard>/Thermal#/Temperatures/

Root Cause : PhysicalContext Schema was missing from redfish schema
metadata

Tested: Redfish validator script passed.

*** /redfish/v1/Chassis/<baseboard>/Thermal#/Temperatures/0
         Type (#Thermal.v1_3_0.Temperature), GET SUCCESS (time: 0)
         PASS
