The Unraid Theme Engine is no longer available, and it doesn't look like it'll ever come back.
I'm not sure what the solution is here, but the documentation will need to be updated once one is found.
There is a new plugin called: "Custom WebUI CSS" by "Wu23333", but I'm not sure if this would work at all.
Solutions that require Docker isn't necessarily the best solution here as many users do not utilise Docker or VM's inside Unraid, and instead opt to use it as a NAS instead.
