False positive in CWE-829 /UntrustedCheckoutMedium.ql

**Description of the false positive**
When there is a workflow that is triggered by a pull_request, this check considers the called workflow to be privileged even though it is not.

**Code samples or links to source code**

Triggered Workflow: https://raw.githubusercontent.com/llvm/llvm-project/refs/heads/main/.github/workflows/release-binaries-all.yml
Called Workflow: https://raw.githubusercontent.com/llvm/llvm-project/refs/heads/main/.github/workflows/release-binaries.yml

**URL to the alert on GitHub code scanning (optional)**

https://github.com/llvm/llvm-project/security/code-scanning/1828

從 CWE-829 /UntrustedCheckoutMedium.ql 查詢開始，檢查報告中連結的 triggered workflow 和 called workflow 範例。將查詢結果與 pull_request-triggered workflow 的行為以及連結的 code-scanning alert 進行比較。完成的標準是 called workflow 不再被錯誤地報告為具有特權。
