Add support for the ppc64le architecture

[Ry6000]

This adds support for building the docker images for the ppc64le architecture. This is used on IBM POWER servers, and also on high end workstations like the Talos II from Raptor Computing Systems.

This adds the architecture to the following workflows:

• java
• installers
• python
• base
• go
• nodejs

For the installer, this adds the new architecture to the multiarch build. For Java, I excluded the architecture from the j9 builds, as support is missing from java_18j9 and java_19j9.

I've been running a bunch of Minecraft servers manually on my Talos II for years, and would love to migrate them all to Pterodactyl!

I'm also opened a pull request to add support for this architecture to wings, which I have successfully compiled for the system: pterodactyl/wings#283

I successfully built the images with Github actions on my own profile: https://github.com/Ry6000?tab=packages&repo_name=yolks , with the exception of the actions that are also failing in master (yolks:debian and games:source). Note that I didn't add the architecture for games, as I don't believe there are binaries for the server software for the games on this architecture.

After modifying the vanilla Minecraft egg to point to my installer docker image, uploading it to the panel, and starting wings built for ppc64e, the server works perfectly!

Please let me know if you have any questions or comments; I am happy more than happy to answer. 😄
