Fails to install on terraform v1.6

[stevenlumos-qz]

Terraform 1.6 appears to have added an extra signature check, which the current provider fails:

$ terraform version
Terraform v1.6.0
$ terraform init -backend=false
...
- Installing mrolla/circleci v0.6.1...
Partner and community providers are signed by their developers.

Bumping my terraform version to 1.6.3 seemed to resolve this for me.
