Auto merge of #12055 - QiangHeisenberg:crates-io-doc-test, r=weihanglo

fix:  doc-test failures

### What does this PR try to resolve?

When I read the source code, I found that the `Registry::new_handle` document test failed and seemed to be missing parameters;

There is no change in this [PR](https://github.com/rust-lang/cargo/pull/10592/files#diff-12973056cf99e8de997011a8738a6740a7dfd06142a73f122f3b35218db37351).
