Describe the fix.

skip_transpilation was removed in V2 primitives, but parts of the docs still refer to them.

1. Should say "If you do not wish to have your circuits further transformed, set the optimization_level to 0"
2. Can remove "When doing so, remember to set the skip_transpilation=True option" since primitives no longer do layout and routing
3. Change "you can skip transpilation in the primitives by setting skip_transpilation=True" to "you can skip further optimization in the primitives by setting optimization_level=0"
