You could install macOS on a Proxmox Server[1]. It's a hell of a procedure and probably more work than just getting an old MacBook Pro 2015 using OpenCore Legacy Patcher[2] to install current macOS. Once you got it working (signing keys etc.), you may be able to use github actions to build and publish your stuff without having a mac present. Unfortunately it won't work forever, so probably it is the easiest way to buy a mac.
