Add `name` attribute to `new Vue` examples in docs

What does this MR do and why?

This MR adds the name attribute to our frontend documentation (and a couple of apps as an example). This encourages any new apps to be created with a name which makes them easier to differentiate when using Vue Devtools. I believe we have encouraged this before but can't seem to find the discussion.
