docs(ai-stack): disambiguate Tesla brand name from Tesla microarchitecture

Browse Source 
"Tesla" was NVIDIA's datacenter-card brand (retired after Volta), spanning
four unrelated architecture generations (Kepler/Maxwell/Pascal/Volta) - a
different, much older thing than the Tesla microarchitecture itself, which
actually predates Fermi/Kepler/Maxwell/Pascal/Volta. Clarify to avoid
reading the power-connector note as claiming Tesla == Volta.
