Auto merge of #13921 - heisen-li:licence_readme_warning, r=weihanglo

fix(toml): Convert warnings that `licence` and `readme` files do not exist into errors ### What does this PR try to resolve? In this PR: - Changed the warning to a hard error and modified the associated test function; - Removed what should have been a redundant test function：`publish::publish_with_missing_readme`； - Since `cargo publish` is preceded by the execution of `cargo package`, the error message in the test `function bad_license_file` needs to be modified. issue: #13629 (comment). ### Additional information It seems that this is not enough, the current situation is that `cargo package` warns if `package.readme` is an empty string or the wrong file location, but if I cancel `package.readme`, no warning is generated. I'm wondering if I should judge `package.readme&licence` when executing `cargo package` and return an error if it doesn't exist? As this has not been done before, your advice is sought.
