Update roadmap to state what was delivered (in past tense)

[danyork]

The roadmap at https://github.com/wordpress-privacy/info/blob/master/Roadmap.md talks a lot about what "will be" available. It doesn't reflect what was delivered in 4.9.6 and later. I am referring people to this page in a presentation when I noticed this.

I see also #19 that suggests re-structuring the roadmap page.

Unfortunately I don't see myself having the time in the next few weeks to do this update to the text, but I wanted to flag the issue in case someone else might have the time.

Hmm... or maybe the page should be updated to indicate that the roadmap is now here:

Hey Dan, an update is underway and need some final editing before we can update pages..

Hey Dan! The core-privacy team has just got the login access to this repo, and we're going to start updating it to reflect our current roadmap and scope of work.

Our V2 roadmap has now been published too; we're really excited for what we'll be doing this year.

We'd love your feedback and input; let's grab a coffee the next time our paths cross.
