2018-07-01-preview for Microsoft.Web/connections seems to be missing?

The 2018-07-01-preview version for Microsoft.Web/connections seems to be missing from https://github.com/Azure/azure-rest-api-specs/tree/main/specification/web/resource-manager/Microsoft.Web ?

It's documented here: https://docs.microsoft.com/en-us/azure/logic-apps/create-managed-service-identity?tabs=consumption#multi-authentication, 2018-07-01-preview should be available as an API version for using the `parameterValueSet` property, but doesn't seem to be - it's not seen as a supported version by the terraform azapi provider, which uses this repo as it's source of truth.

Start in specification/web/resource-manager/Microsoft.Web and compare its available API versions with the linked Microsoft documentation for Microsoft.Web/connections and parameterValueSet. Check the related Terraform AzAPI issue for expected behavior; done means the 2018-07-01-preview version is represented and recognized as supported.
