Update account owned tokens

[jhutchings1]

Summary

👋🏻 I made some quick updates to the account owned tokens page to reflect:

1. Update description to reflect GA status
2. Add procedural instructions
3. Sort the compatibility matrix alphabetically

One piece that I wasn't sure how to do properly was link to an API that's only documented in the beta docs site (at least I couldn't find it on the regular site). @crwaters16 not sure if you have thoughts on the best way to do that.

Screenshots (optional)

Documentation checklist

• The documentation style guide has been adhered to.
• If a larger change - such as adding a new page- an issue has been opened in relation to any incorrect or out of date information that this PR fixes.
• Files which have changed name or location have been allocated redirects.

Good q @jhutchings1 - if it's appearing in vNext but not on the existing site, that's a bug to the existing site. We're doing the site cutover on Monday, so the easiest path forward is to omit the link to that endpoint for now and add it in on Monday/Tuesday. Using the fully qualified link to the /api-next/ in the interim should also work, though.

We can sit on this PR until next week if it makes life easier.
