Subject: [PATCH] [rehype-react] Add Fragment option, update which options are
 optional (#41600)

* [rehype-react] Add Fragment option

Usually this will be `React.Fragment`, but it accepts any component.

* [rehype-react] Update which options are optional

Most options have healthy defaults. Only `createElement` is required.

* [rehype-react] Update version number

* [rehype-react] Update tests to include Fragment option
