Fix first page of New Flutter Project Wizard to be meaningful

[pq]

Removing the old custom wizard step exposed one inherited from the framework.

Needless to say it adds no value but I can't see a way to remove it.

I think we need to specify something...

• a blurb about flutter?
• project level settings? (are there any?)
• a picture of the team? 😄

A blurb at the top sounds great - it'll help give the user context.

Perhaps also a way to configure the flutter sdk? That may be a step we want to help streamline the getting started process.

Any chance of combining the current two pages into a single page?

So.... Looking at more (err) exemplars (go, rust, elixir, erlang), it's not uncommon to be greeted with a frameworks page (often empty) as we are here. While we could make this smoother maybe, it's not so bad (hence bumping from bug to enhancement).

Perhaps also a way to configure the flutter sdk?

This seems like a good idea. And in the spirit of #54, we could do some validation here too.

I wish! Both of these pages are conjured magically by the framework and I don't see an easy way (or any way) to merge. Still investigating...
