tools/power/x86/amd_pstate_tracer: Fix python gnuplot package names

The prerequisites section listed non-existent packages
"phython-gnuplot" and "phython3-gnuplot", which may mislead users and
cause installation failures.

Update the names to the correct distribution package names
"python-gnuplot" and "python3-gnuplot", helping users avoid confusion
and saving time for those following the instructions.
