Guide: TransitionGroup page falsely implies Transition renders a wrapper element

[cartr]

The "TransitionGroup" page of the guide includes the following text:

Differences from <Transition>

<TransitionGroup> supports the same props, CSS transition classes, and JavaScript hook listeners as <Transition>, with the following differences:

• By default, it doesn't render a wrapper element. But you can specify an element to be rendered with the tag prop.
• [...]

This implies that <Transition> does render a wrapper element. But actually, in Vue 3, it appears that neither <Transition> nor <TransitionGroup> renders a wrapper element by default, so this isn't really a "difference".

(This language seems to have been introduced by #649.)

I'm new to Vue, so maybe there's something I'm not understanding here, but it seems like this should maybe be revised to say something like:

• A tag prop can be passed to render a wrapper element. (By default, <TransitionGroup> doesn't render a wrapper element, similar to <Transition>.)
