fix: iac usage tracking missing custom org

[rontalx]

What does this PR do?

Fixes an issue in IaC usage tracking where it was not passing the org data to Registry, causing it to count for the default org instead of the custom set org.

How should this be manually tested?

• Run registry locally.
• Create another org in the Admin UI.
• Set the CLI to point to the local registry API.
• Set the CLI to the custom org you created, either via the env SNYK_CFG_ORG variable or the --org flag.
• Make a CLI scan to an IaC file.
• See in the UI that the test-count was increased to the default org instead of the custom one.

With this branch, the correct test-count for the custom org will be increased.

Any background context you want to provide?

1. This came up in a Customer Support Ticket, when a customer was using the VS-Code plugin with a custom org to scan IaC files, they mentioned that scan counts are increased for wrong organization. I was able to replicate this quickly and worked on a solution.

2. I've also validated this solution with VSCode and made sure it resolved the original issue.
   To try the solution in VsCode, generate a custom snyk-macos binary from the CLI using the Make file and point the plugin in VSCode to it via the advanced settings.

3. This did not happen when fetching org-settings as the correct query-string data was passed:
