Citra - Any full GitHub organization mirrors?

I'm trying to find links to full mirrors of Citra, but I can't find any of the extra repos Citra hosted (like the build environment with docker files, the GitHub wiki with all of the documentation, etc.)

I found this but it looks like it only has the Citra code for now. Does anyone have a backup of those other repos?

I was hoping to learn more about emulation development on an eventual successor like Lime3ds and maybe contribute toward getting the CI builds working again. If this isn't the right community for this question, I can remove it. I wasn't sure if there was a good place to ask questions on the development side of things.
