LGTM.

Detailed notes

In the Azure provider we are using 1.2 is the default. And come Nov 24 it will become the minimum (docs).

Also, as this is for saving Terraform state, we do not need to configure clients to use TLS 1.2. (docs)

According to AzureRM Provider Version v3.0 docs about azurerm_storage_account: The default value for the field min_tls_version will change from TLS1_0 to TLS1_2.

We have been using Version v3.0 since late 2022 (PR) when we release release 2022.10.1 came out. As the release notes say, this was a breaking release. So we are good.
