[BUG] Add property http20ProxyFlag to SiteConfigProperties in Azure.Provisioning.AppService

[ShilpiRachna1]

Library name and version

Azure.Provisioning.AppService 1.0.0

Describe the bug

To support GRPC endpoint in AppService, we need to expose two properties in SiteConfig:
http20Enabled and http20ProxyFlag. Currently, http20ProxyFlag is missing and so it is not possible to enable GRPC endpoint in AppService using Azure.Provisioning.AppService library

Expected behavior

Property http20ProxyFlag added to SiteConfigProperties

Actual behavior

Property http20ProxyFlag missing in SiteConfigProperties

Reproduction Steps

Try to create WebSite object using Azure.Provisioning.AppService:

var webSite = new WebSite("webapp")
{
Name = DashboardHostName,
AppServicePlanId = appServicePlanId,
SiteConfig = new SiteConfigProperties()
{
LinuxFxVersion = "SITECONTAINERS",
IsHttp20Enabled = true,
// No property exists for http20ProxyFlag
}
};

Environment

.Net 9
