feat(aio): add marketing class to AppComponent <aio-shell> on mkt page

[wardbell]

Also navigation.json Doc page should be hidden in sidebar, shown in top-menu when top-menu is displayed in the sidenav (hidden now).

Sure these could be separate PRs. Both changes are tiny. Let's get on with it.

Remember to run yarn docs locally as this PR changes docs and navigation.json.

These could be separate PRs, indeed, but if in a single PR they really should be separate commits no?

[petebacondarwin]

The changes to hidden stuff LGTM

The changes to adding the marketing css class would be simpler via a HostBinding I think:

@HostBinding('class.marketing') get isMarketing() { return !isSideNavDoc; }

[petebacondarwin]

Lovely! Please squash

[wardbell]

I don't know if actually simpler (personally don't think so) but certainly more Angular idiomatic. Added in the 2nd commit.

Btw, I used an isMarketing field rather than a getter because (a) it seems more clear to me and (b) it is marginally more performant ;-)

I don't disagree with your point about separate commits ... having raised it myself ... but I've seen worse from absolutely everyone. Is it a blocker? I hope not.
