Unable to provision spaces bucket in certain regions where it is available

[alephtwo]

I'm trying to provision a new Spaces bucket in TOR1 and am currently blocked by the region allow list:

https://github.com/digitalocean/terraform-provider-digitalocean/blob/f650bc286dc0bccf874b07966723a5548384d55f/digitalocean/spaces/spaces_buckets.go#L15

This list should probably be updated to account for which regions support Spaces currently.

Good catch, Ben! We need to add tor1 to this list.
