change outboundIPAddresses to outboundIpAddresses (#20846)

Issue: live validation catch mismatch property name between swagger and service response;
Fix:  change swagger to outboundIpAddresses
Considerations: 1) statistic more traffic from ARM than SDK, trying no break REST users 2) Other RP(Microsoft.Web) have same property also named as outboundIpAddresses.
