Nix-community infra got an EPYC upgrade

[zimbatm]

Hey community,

Thanks to your donations, we could update the CI machine to more powerful beasts. We were hitting the limits of the current hardware and this will buy us some room for everybody.

We updated our main CI builder from a machine with a Ryzen 9 3900 CPU (12 cores), 128gb ddr4 RAM, 2x1.92tb NVME to a machine with an EPYC 9454p CPU (48 cores), 256gb ddr5 and 2x1.92tb storage.
The previous hardware is now accessible as a remote builder for the community and replaces the old machine (ryzen 5 3600 6 core, 64gb ddr4, 2x512gb).
This speeds up CI for our other countless projects

Thanks to everybody who donated, this project wouldn't be possible without you.

Best,
The infra team
