Auto merge of #14121 - dieterplex:redact-file-num, r=weihanglo

test: Auto-redact file number

This is from <#14096 (comment)>.

Although the number of files in `cargo package` is important,
we have `validate_crate_contents` and `validate_upload_with_contents`
that verify the exact contents.
Redacting `Packaged` status should be fine.
