MSRC benign validation: VersionCalPRComment label handling

[Yigods]

Benign MSRC bounty validation PR for GitHub Actions workflow behavior.

This PR is not intended for merge. It changes only src/account/setup.py to validate whether the Release Version Calculation pull_request_target workflow can consume PR-controlled artifact outputs and apply/remove PR labels with GITHUB_TOKEN. No secrets are read or exfiltrated. The PR will be closed after evidence is collected.

Hi maintainers, this is a benign MSRC security validation marker: attempting to remove blocking labels via VersionCalPRComment artifact output. No merge intended.
