There are errors in the launchable which is a tool to analyize the unit tests. There are errors, but it was not raised. And the CI cases passed. However, I want to suppress the errors. The reason is maybe the `actions/setup-python` used in the logic doesn't ppc64le/s390x. And the solution is to skip the logic in these cases.

I am working in the PR <https://github.com/ruby/ruby/pull/14721>. If I can not fix it by myself, or it takes more time, I will ask the maintainer of the launchable in the Ruby project.
