[jakedoublev]

Proposed Changes

• Fixes: https://github.com/opentdf/platform/actions/runs/18209372213

[Invalid workflow file: .github/workflows/nightly-checks.yaml#L80](https://github.com/opentdf/platform/actions/runs/18209372213/workflow)
The workflow is not valid. .github/workflows/nightly-checks.yaml (Line: 80, Col: 3): Error calling workflow 'opentdf/platform/.github/workflows/checks.yaml@main'. The nested job 'tests-bdd' is requesting 'id-token: write', but is only allowed 'id-token: none'.
