upgrade-provider fails when the provider doesn't have a release yet.

[ringods]

What happened?

Helping a partner with bridging their provider. They ended up with a compile error because of a version mismatch between some of the required Pulumi packages. I wanted to use upgrade-provider to get it back in sync, but it fails because the provider doesn't have a Github release/tag yet.

Example
