Documentation Missing for Inputs to the GCP Provider

[automagic]

On this page: https://www.pulumi.com/registry/packages/gcp/api-docs/provider/

Many of the input fields are missing documentation descriptions that are present in the terraform docs about provider configuration: https://registry.terraform.io/providers/hashicorp/google/latest/docs/guides/provider_reference

There is useful information in those docs that would be helpful to have in pulumi docs, such as:

• https://registry.terraform.io/providers/hashicorp/google/latest/docs/guides/provider_reference#quota-management-configuration
• https://registry.terraform.io/providers/hashicorp/google/latest/docs/guides/provider_reference#provider-default-values-configuration
