ringabout 48d71e7ead fixes nightlies due to UB errors; increase maxCPU hard limits (#25219)
ref https://github.com/nim-lang/Nim/pull/25217

The issues is actually that there is a hard limit for max cpus in
niminst: https://github.com/nim-lang/Nim/pull/25219, which set to 20
while there is a 21 cpus now
