GPG Key Validation incorrectly reports that user is NOT a member of an org

[Yantrio]

For some reason, the detection logic is failing. For an example see this PR: #792

If we manually hit the github api endpoint, it returns a 204 so the membership should be detected just fine.

Hey @Yantrio, I just checked this issue on the latest main and it seems to be working as expected. I think we can close this issue.

(base) ➜  src git:(main) go run ./cmd/verify-gpg-key -key-file=/tmp/nspadaccino-pgp-key -username=nspadaccino -org=VinylDNS
## Validate GPG key
### Key is a valid PGP key
✅ **Success**
### Key is not expired
✅ **Success**
### Key is not revoked
✅ **Success**
### Key can be used for signing
✅ **Success**
### Key has a valid identity and email. (Email is preferable but optional)
✅ **Success**

## Validate Github user
### User is a member of the organization VinylDNS
> [!NOTE]
> If this is incorrect, please ensure that your organization membership is public.

✅ **Success**

Could have been a transient issue, perhaps it took a bit for the membership public status to propagate to different API nodes? Thanks for checking @diofeher!
