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.

**"Tesla"-branded card power connector — don't assume standard PCIe.**
("Tesla" here is NVIDIA's old datacenter-card *brand name*, retired after
Volta — not the unrelated, much older Tesla *microarchitecture* that
predates Fermi/Kepler/Maxwell/Pascal/Volta. V100/P100/P40/M40 all shipped
under the Tesla brand despite being four different architecture
generations.) These PCIe cards take an 8-pin **CPU/EPS12V** connector, not
the 6+2-pin PCIe
connector a normal GPU uses — a standard PCIe cable will not plug in. Get the
dongle/adapter (splits a PCIe 8-pin into EPS12V, or use a real EPS cable) and
never daisy-chain both 8-pin rails off one PSU cable/splitter — use two
