CI: Launchable: Fix errors at actions/setup-python on ppc64le/s390x

The following errors happened at the actions/setup-python step.

https://github.com/ruby/ruby/actions/runs/18229870239

> The version '3.x' with architecture 's390x' was not found for Ubuntu 24.04.
> The list of all available versions can be found here: https://raw.githubusercontent.com/actions/python-versions/main/versions-manifest.json

> The version '3.x' with architecture 'ppc64' was not found for Ubuntu 24.04.
> The list of all available versions can be found here: https://raw.githubusercontent.com/actions/python-versions/main/versions-manifest.json

After skipping the actions/setup-python step, the following errors also
happened at the actions/setup-java step.

https://github.com/ruby/ruby/actions/runs/18355975425?pr=14721

> make-ibm (check, ubuntu-24.04-ppc64le)
> Could not find satisfied version for SemVer '17'.

> make-ibm (check, ubuntu-24.04-s390x)
> The process '/usr/bin/bash' failed with exit code 1

> make-ibm (check, ubuntu-24.04-s390x)
> Process completed with exit code 127.

To fix the errors, I started using the Java distribution semeru (IBM Semeru
Runtime Open Edition) on the ppc64le/s390x cases.

You can see the following page for the details of the Java distribution semeru.
