update nsx-t-rout-table-endpoint

[appdess]

Hi, sorry opened this before wrongly. I updated the NSX Endpoint and validated that i am able to get the routes with the new endpoint from a VMC environment. Seems the API-Endpoint did change slightly. NSXT_ROUTING_TABLE_URL="${NSXT_PROXY_URL}/policy/api/v1/infra/tier-0s/vmc/routing-table?enforcement_point_path=/infra/sites/default/enforcement-points/vmc-enforcementpoint"
