This PR extends sdk-gen for .NET to support parameterized providers.
When a schema has a parameterization, we emit a new function
`PackageParameterization()` in the `Utilities` class and call this
function for generated resources, invokes and methods.
It requires https://github.com/pulumi/pulumi-dotnet/pull/311 to be
merged first and a new version of Pulumi nuget package to be released,
then we can bump the version we use here.
EDIT: Now using Pulumi nuget package v3.66.0 ✅
