This adds a `/* @jsxFrag mdx.Fragment */` next to the existing `/* @jsx mdx */` pragma. From MDX runtimes, this exports as `mdx.Fragment` either `React.Fragment` or `Preact.Fragment`. Vue 2 does not support fragments, but as JSX and hence MDX is already specific to React or Vue, well: folks shouldn’t use fragments in MDX files targeting Vue. As we have fragments, we can also use that to pass children through missing components: `<>{props.children}</>`. This fixes runtimes where HTML is not available, such as React Native. But, as Vue doesn’t like that, there’s a hidden flag to still use the original behavior: `<div {...props} />`. Still, there remains a difference in frameworks: Vue does not put `children` in `props`, so `{...props}` has never passed children along in Vue. Closes GH-972. Closes GH-990. Closes GH-1014.

As we have fragments, we can also use that to pass children through
