Examples in docs (Spectrum) unclear

[ivanjeremic]

Examples like this one one the https://react-spectrum.adobe.com/react-spectrum/DialogContainer.html#visual-options Are not very helpful because copy pasting that code does not work, where do <Edit/> & <EditDialog/> come from where is the rest? Examples should ideally work just by copy pasting the examples.

Edit and EditDialog are defined in previous examples on the page. This was just done to avoid being repetitive. We could definitely improve this to be more clear though.
