Right now there are people who come to MusicBrainz looking a JSON API and they will skip right over "XML web service". To address this we should:
- Rename XML Web service into "MusicBrainz API" in our relevant documentation pages.
- Add needed doc page redirects to not create dead links.
- Update the Product menu items accordingly.
- Remove any last references to JSON API being in Beta, if any.
No functionality needs to change, we just need rename our services to reflect what people are looking for.
