Enable private vulnerability reporting for rv

[snoopysecurity]

Is it possible to enable vulnerability reporting for rv? https://docs.github.com/en/code-security/how-tos/report-and-fix-vulnerabilities/configure-vulnerability-reporting/configuring-private-vulnerability-reporting-for-a-repository. Or its worth adding a security.md with details regarding how to contact maintainers for reporting security issues.

I have enabled reporting on this repo, and opened a PR to add SECURITY.md. Thanks for the suggestion!
