Auto merge of #11995 - ehuss:s-triage-label, r=weihanglo

Add S-triage auto-label.

This automatically adds the https://github.com/rust-lang/cargo/labels/S-triage label to new issues using the template.

This is intended to help make it clear that issues have not been triaged, and need some decision on the next state they should go to.
