fix: export MatchContainer from react-relay package

[giautm]

When playing with Client 3D, I found the MatchContainer's props is exported, but the component didn't. So this should fix the problem.

https://github.com/giautm/relay-3d-example/blob/d479ba493d9c39e3946d12fcffb7c7a1f3977f2d/directories-3d/components/common/RelayMatchContainer.tsx#L2-L4

The document said it should exported from react-relay package:

relay/website/docs/guides/data-driven-dependencies/server-3d.md

Lines 111 to 114 in fe7af88

	```js
	const {useFragment, graphql, MatchContainer} = require('react-relay');
	function CommentRenderer(props) {

Any update there?
