Upgrade opentofu fork dependency to support ephemeral values #730
Description
While attempting to fix #708, I tried to use the latest rds module in a local run. It can't be turned into an SDK because we use [this commit](pulumi/opentofu@3146dac on pulumi-main of our opentofu fork to generate pulumi modules.
We then get the following error:
error: failed to get schema: parameterize: rpc error: code = Unknown desc = error while inferring module schema for 'terraform-aws-modules/rds/aws' version 7.1.0: error while loading module terraform-aws-modules/rds/aws: /var/folders/87/6b426tw97kl6vb55pl6nbzym0000gn/T/pulumi-terraform-module/workdirs/by-module-source-and-version/terraform-aws-modules%2Frds%2Faws/7.1.0/.terraform/modules/mymod/variables.tf:172,3-12: Unsupported argument; An argument named "ephemeral" is not expected here.
We need to resync/upgrade our fork and point this tool's go.mod at it.
