spinupwp-plugin Not using SpinupWP notice

I've added the required logic to SpinupWP so that we can identify sites that aren't hosted using SpinupWP. @bradt as per our meeting, do we want to add a notice for those users which install our plugin?

If so, are we using a generic dashboard-wide notice?

Yes, I think a dashboard-wide notice makes sense. Perhaps @lizDB can help you with the copy?

How about:

It looks like this site isn't hosted with SpinupWP. Before this plugin can do anything, you'll need to add this site to your SpinupWP server. Not a SpinupWP user yet? Sign up

Could do with an appropriate doc link on for adding the site to a SpinupWP server?

(also note the tags on the link)

I've updated the link above to be "Sign up" instead of "here"
