Description

The github.com/hashicorp/terraform-plugin-sdk/v2/helper/schema.Resource.Update field is deprecated in preference of the context-aware UpdateContext. The new functionality is not available in version 1 of the Terraform Plugin SDK so this check should only flag version 2 usage of Update.
