Update Vuex docs to remove reference to createLocalVue
What does this MR do?
In #220482 we note that some docs are out of date.
This MR updates the docs for Vuex to remove the reference to createLocalVue (and the subsequent localVue variable).
See the review app for the changes as they would look when deployed.
It doesn't seem harmful to remove it from our "recommended" test setup, but it is actively confusing to leave it.
In addition to removing the unnecessary code, this MR also adds a note for people who might find createLocalVue and want to understand why it's not used any more. That note also links to the deprecation issue (linked above) to complete the loop.
