Document the migration path from Terraform Cloud to a standard backend

### Terraform Version

```shell
1.4.6
```

### Use Cases

After the [recent announcement](https://www.hashicorp.com/blog/terraform-cloud-updates-plans-with-an-enhanced-free-tier-and-more-flexibility) which introduces a resource limits for free tiers, I'm planning to migrate my state(s) off of Terraform Cloud.

However, when I tried to migrate to any other backend, I get the following error:
```
Error: Migrating state from Terraform Cloud to another backend is not yet implemented.
```

Could you please share a detailed step-by-step process on how to safely migrate away?

### Attempted Solutions

Traditional migration to an S3 backend, which fails.
