Addon-docs/Vue: Fix string docgen

[tmeasday]

Issue: #14056

What I did

Ensure we don't accidentally try and fix react-docgen-typescript when we are in vue

How to test

1. There is a test for what the input looks like in vue3
2. There is also a story in vue3, although it should be noted we don't current ever look at these stories :/

So the presence of func means we're in vue? Seems a little brittle, but the real solution is probably a major refactor so I can live with it.

Is func always false in these cases?

[tmeasday]

I suppose func is probably true when you are using one of them vue default value "generators". I haven't explored the full space of everything vue can do though :/

Yeah, given the plan is to drop all this default value shenanigans in 6.3, my feeling is we just do what's easiest for now, especially given a refactor this close to 6.2 would be a bit scary.

LGTM!
